From cf25ddc8b31ef883cf23eeb8d2eae21535a98002 Mon Sep 17 00:00:00 2001

Subject: [PATCH] git-gui: Refactor single_commit to a proc.

This is a minor code cleanup to make working with what used to be the
$single_commit flag easier.  Its also to better handle various UI
configurations, depending on command line parameters given by the
user, or perhaps user preferences.
