From: Pat Notz Date: Tue, 2 Nov 2010 19:59:07 +0000 (-0600) Subject: commit: helper methods to reduce redundant blocks of code X-Git-Tag: v1.7.4-rc0~90^2~5 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a6fa59924d154f2dcfc331357bf553e043aa0242;p=git.git commit: helper methods to reduce redundant blocks of code * builtin/commit.c: Replace block of code with a one-liner call to logmsg_reencode(). * commit.c: new function for looking up a comit by name * pretty.c: helper methods for getting output encodings Add helpers get_log_output_encoding() and get_commit_output_encoding() that eliminate some messy and duplicate if-blocks.
