From 6df514af9dfb44f104baa9b581e91de22af89b8d Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Sun, 22 Mar 2009 19:14:02 -0700 Subject: [PATCH] format-patch: construct patch filename in one function reopen_stdout() usually takes the oneline subject of a commit, appends the patch suffix, prepends the output directory (if any) and then reopens stdout as the resulting file. Now the patch filename (the oneline subject and the patch suffix) is created in get_patch_filename() and passed to reopen_stdout() which prepends the output directory and reopens stdout as that file. The original function to get the oneline description, get_oneline_for_filename(), has been renamed to get_patch_filename() to reflect its new functionality.
