Junio C Hamano [off-list ref] writes:
Neither has [4/4] on it. I'd like two patches so that: * [PATCH 1/2] applies to bc/maint-diff-hunk-header-fix, so that the languages in 1.6.0.2 are fixed for non GNU platforms; * After applying [1/2] to bc/maint-diff-hunk-header-fix, I'll merge the branch to bc/master-diff-hunk-header-fix and then... * [PATCH 2/2] applies on top of it to convert new languages that are supported only on 'master' to use xfuncname.
Here is [1/2] to be applied on top of 45d9414 (diff.*.xfuncname which uses "extended" regex's for hunk header selection, 2008-09-18). Testing appreciated. -- >8 -- Subject: [PATCH] diff: use extended regexp to find hunk headers Using ERE elements such as "|" (alternation) by backquoting in BRE is a GNU extension and should not be done in portable programs.
