This teaches ce_path_match() to use the match_pathspec() used in git-ls-files, which knows about glob patterns. Signed-off-by: Junio C Hamano --- [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.
