Subject: [PATCH] git-gui: Support LFs embedded in config file values

Using the new --null option added to git-config in git 1.5.3 we
can safely accept LFs that are embedded in configuration options.
This does require a completely different configuration file parser
then the pre 1.5.3 version as we are splitting on very different
values.
