Patterns don't apply as expected in pipe mode

[Altreus]

The following pattern successfully matches real files, but not pipes.

[CSSUnminify]
select = *.css

Produces:

$ tidyall path/to/existing/file.css
$ tidyall -p anything.css
test
^Dtest
No plugins apply for 'anything.css'

(I've inserted a ^D where I literally pressed ^D)

However, it works fine with an extended zglob, thus

[CSSUnminify]
select = **/*.css

$ tidyall -p anything.css
test
^Dtest

The difference is there's no warning (it is irrelevant whether the input file is valid according to the plugin).

I think the issue is probably that anything.css ends up getting turned into something like ./anything.css internally.

I wonder if this would be better as a doc fix that encourages the use of zglob patterns everywhere, since they're far more likely to do what you want anyway.

Hmm, or maybe that's not it. Anyway, if you could write a test case that'd be helpful. I'll try to investigate this when I have tuits, but those are in short supply.
