spells.c: breath() could do damage on the other side of walls, added an los()
	call to prevent this

	be handled separately
---------------------- 11/1
moria1.c: when wearing object and must remove current object, fix code to

	leave cursor on msg line while entering repeat count

	monsters average max hp instead of level
--------------- 11/15
save.c, undef.c: restore_stats function eliminated, replaced by call to read
	py.stats from file, other fixes to get restore code working
creature.c: if creature never moves, kill it if it happens to be in a wall

creature.c: in mon_move, return immediately if creature is killed because it
	is in rock

	is wrong, now save value before calling mon_take_hit()
moria2.c: turn find_flag into a counter, when it reaches 100, exit find mode
	with message "You stop running to catch your breath.", prevents
	infinite loop
generate.c: fixes to help prevent isolated rooms, in build_tunnel() make

	in cave_gen(), copy [yx]loc[0] to [yx]loc[k] so that can build tunnel

	to monster_name() call
externs.h, creature.c, moria2.c, spells.c: removed seen argument from
	mon_take_hit, as it was used inconsistently, only get credit for a
	kill if monster is visible when killed

	always FALSE, added monptr, to fix the m_list bug
creatures.c: new m_list code fails when call delete monster from within
	creatures(), fixed it by changing some calls to delete_monster()
	to call delete_monster() only if the dead monster is between the
	current monster and mfptr, otherwise, call fix1_delete_monster()
externs.h, creatures.c, spells.c: breath() has new argument monptr, to fix
	the m_list bug
externs.h, creatures.c, spells.c: two new functions, fix1_delete_monster()
	and fix2_delete_monster() which together equal delete_monster,
	these are called from within creatures() when a monster is killed
many: eliminate the fopen field since I had 5 bitfields in the cave structure,
	and it is much easier to only save 4, added a BLOCKED_CORR case for
	secret/closed/locked/stuck doors and rubble, all code that used
	to test fopen now tests fval, most code that used to set fopen is
	now gone since it was redundant with fval setting code
moria2.c: fixed disarm() so that if there is a valid trap to disarm, it will
	print "Something/monster_name is in the way!" just like close door."
generate.c: place_stairs() could place them on the boundary, make sure
	that x/y can never be 0 or cur_xx-1, also, in town_gen(), call place_

moria2.c: fixed openobject() so that if there is something to open, it will
	print an message just like closeobject if there is a monster in the way
save.c: fix another save file problem, noscorefile defined as int in get_char,
	just eliminated it and use noscore instead
--------------------------- 11/22

	all pusht calls changed to delete_object where ever appropriate, etc.
---------- 11/29
misc1.c: increase p1 value for crowns of seeing by multiplying by 5
----------- 12/4
creatures.c: change stealth code, instead of randint(10) < stl, it now cubes
	randint(64) and compares against 1 << (17 - stl), the result is that
	a change of one in stl always decreases monster notice chance by 80%,
	and perfect stealth is impossible
wizard.c: allow wizard to enter any stealth between -1 and 17
save.c: extensive changes to save code competed, save files are now xor
	encrypted, and are supposedly portable, all savefile protection code
	is gone

various: check use of "?", especially in get_check() and verify() prompts,
	verify changed to replace the period with a question mark
spells.c, creature.c, misc1.c: breath(), update_mon(), and loc_symbol()
	changed to use blind status bit instead of blind counter, this
	helps make the display look better, i.e. nothing disappears until

monsters.c: more monster fixes from DJG
monsters.c, misc1.c, moria2.c, treasur1.c: change (SM) to (SA),
	slay monster to slay animal

	constants to defines
save.c: add error exits to every loop/array index in the get_char()
	routine to prevent crashes due to bad save files
store1.c: in item_value, set value to zero if known cursed, this prevents
	store from buying known cursed items
------------ 12/7
store2.c: remove switches in prt_comment*() functions, replace with table
	look up to get proper string, saves much code space
creature.c: changed stealth code again, if resting/paralyzed monster has a
	chance of noticing once every 50 turns instead of never like before,
	change 64 to 1024, and 17 to 29 for a better distribution
constant.h, save.c: read noscore variable from savefile of dead character, now
	only read/write noscore for live characters, changed patch_level to
	9 so that old savefiles can still be read
save.c: in get_char(), the loop error prevention code was missing two gotos
store2.c: get_haggle(), when check for valid first use of incremental haggle,
	ignore leading spaces in the string
moria2.c: add_food() should increment slow value, not just set it when bloated
save.c: when can't create savefile, test for from_savefile before giving
	wizard message "Overwrite old?", when exit in wizard mode do the
	"readable to all?" check after closing the file
save.c: from_savefile set wrong, should always be set if have read from a file
	not just when a complete character is read
moria2.c: bash(), do not put character off balance if bash is successful
misc2.c: get_spell(), instead of beeping for unknown spell, print a message
recall.c: for monsters with sleep value of 0, could never learn that fact,

-----12/9
dungeon.c: call disturb when player takes poison damage, or starvation
	damage
variable.c: change the three doors from 'a ...' to '& ...', needed because
	of wall-to-mud wand
wizard.c: create_object wrong, was calling popt() then delete_object() then
	setting c_ptr->tptr, this fails because the delete objects will move
	the location (in t_list) of the just created object will change
treasur2.c: change 'nothing' item to be stackable, so that it can be safely
	picked up
save.c: was calling store_maint before objects were reidentified, this caused
	stores to end up with multple entries for stackable identified items
externs.h, misc2.c: new function inven_check_weight(), check toosee whether
	picking up an object will change the players speed
moria2.c: carry(), if picking up an object would slow you down, prompt with
	question "Exceed your weight limit?" to give player a choice
moria2.c, misc1.c: only show rock types in look() if highlight_seams option
	is set, also change option text from "highlight" to "HL and notice"
spells.c: in fire_bolt() and fire_ball(), set recall info if monster takes
	extra damage because of weakness or reduced damage because of breath,
	in dispel_creature() set EVIL/UNDEAD flag if creature hurt,
	in turn_undead() set UNDEAD if creature hurt, in drain_life() set
	CD_UNDEAD if creature not hurt
recall.c: "may carry one or two treasures" needs the plural, but the others
	remain singular/collective
------------- 12/11

	stealth to 18
monster.c: white worm mass sleep value from 10 to 1, crystal ooze 60 -> 1
creature.c: in drain mana spell, if r1 greater than cmana, then set r1
	equal to cmana to limit creature's hp gain
recall.c: when print out creature attacks, exit loop if i >= 4, caused
	problems for umber hulk, etc. which have 4 attacks
store1.c: instead of destroying all single stackable objects, only destroy
	one half on average (randint(number)), makes store 1 and 5 inventories
	look better, oil is much more common, identify a little more common
treasure2.c: accidentally change blank_treasure tval earlier, set tval
	back to 0, and set subval to 64
store1.c: change store_carry(), for group items, must update scost; for any
	stackable item, set ipos so that inventory will scroll to show it;
	let group items (except torches) stack over 24 since each group is
	created with a set number to begin with; ipos must be set to -1 at
	start not 0;
store2.c: store_sell(), pass a pointer to cur_top instead of just its value,
	if sold object not on the page shown, scroll to show the object
------------ 12/13

	from 0 to 3, fixes bug with knowdamage(), add variable j to count
	attacks actually printed out
save.c: put limit on number of times store inventory changed in get_char()
store2.c: rewrite incremental haggle code again, add new parameter 'num_offer'
	to receive_offer, change get_offer parm last_offer to num_offer, only
	allow inc haggle if num_offer != 0; must reset new_offer after
	rejected offer in recieve_offer and sell/purchase_haggle
------------ 12/14
misc2.c, lots: change way spell learning works, new command 'G'ain magic
	spells, new function gain_spells() in misc2.c formerly part of
	calc_spells(), new status flag PY_STUDY controls printing of 'Study'
	in status line, new field py.flags.new_spells number of spells can
	learn
origcmds.hlp, roglcmds.hlp: document the 'M'ap and 'G'ain magic commands
