Currently, these do not work:
git diff-files 't/*.sh'
git diff-index HEAD 'xdiff/*.c'
git update-index -g 'Documentation/howto/*.txt'
This is because ce_path_match(), the underlying function that is used to
see if a cache entry matches the set of pathspecs, only understands
leading directory match.
This teaches ce_path_match() to use the match_pathspec() used in
git-ls-files, which knows about glob patterns.

[SORRY FOR A RESEND -- I screwed up the To: field of the previous message]
* Having two different behaviours of pathspec matching has been
bothering me for quite some time. The changes here look trivially
correct and the result passes all the tests, but this is quite close
to the core part of the system, and would benefit greatly from extra
set of eyes.
This patch does not touch the tree walker, and does not affect
diff-tree nor ancestry pruning done in the revision traversal. That
however is even closer to the core and is performance critical. It
needs to be done carefully not to descend into trees that would never
match needlessly. IOW, not today.
