OK
I was wondering about supporting _both_ globs and re's
right now my ignore file has a # to precede comment lines
maybe re: precedes regexp lines and unadorned lines are globs.

However the re's provided by regex(7) are too weedy to be worth
bothering with.
If however, there is a serious plan to go to perl, it may be worth
providing for this now in the ignore syntax.

Additionally this causes problems with sharing the same exclude file as
used by git.
However...
I really think git's exclude file capability and cogito's are different.
Cogito is aiming to provide full-blown SCM capabilities - git isn't

I am also concerned that a centralised ignore file is not flexible enough.
Certainly limiting if we support globs only.
It may be that you want different rules in different trees - someone on
lkml mentioned that excludes vary in different parts of the source.
Eg .s files may be generally ignored - but not in the asm parts of the tree.

Also... you haven't mentioned perl for a while - can you give us an update?
I personally think we're making life needlessly unpleasant by sticking
with shell.
