fix nextline indentation when has // in code

[sleetdrop]

for example:
iconv("GBK", "UTF-8//IGNORE", $str);
the next line will indent

This fails on the line:

iconv("GBK", "UTF-8//IGNORE", $str); // test

There are a few other cases as well but they were more contrived than this one.

Unfortunately I think this is just one of those edge cases that isn't possible to fix with the current implementation of the indention system, closing issue.

A heuristic fix could be to require (^|\s) before //. Should probably search some large PHP code bases first, to see if anyone does line comments without leading whitespace.
