[PATCH 1/3] cg-commit: Move author picking to cg-Xlib

From: Jonas Fonseca <fonseca@diku.dk>
Date: Feb 7, 2006, 22:44 UTC
Message-ID: <20060207224419.GA24790@diku.dk>

Adds pick_author utility function to cg-Xlib that uses the author line from git-cat-file output to print a string that sets the GIT_AUTHOR_* env variables. This string should then be eval'd by the caller.
