Subject: [PATCH 07/10] pickaxe: merge diffcore_pickaxe_grep() and diffcore_pickaxe_count() into diffcore_pickaxe()
Date: Sat, 22 Mar 2014 18:15:57 +0100	[thread overview]
Message-ID: <1395508560-19893-8-git-send-email-l.s.r@web.de> (raw)
In-Reply-To: <1395508560-19893-1-git-send-email-l.s.r@web.de>

diffcore_pickaxe_count() initializes the regular expression or kwset for
the search term, calls pickaxe() with the callback has_changes() and
cleans up afterwards.  diffcore_pickaxe_grep() does the same, only it
doesn't support kwset and uses the callback diff_grep() instead.  Merge
the two functions to form the new diffcore_pickaxe() and thus get rid of
the duplicate regex setup and cleanup code.
