Subject: [PATCH] git-gui: Automatically toggle the relevant radio buttons.

When the user selects a starting revision from one of our offered popup
lists (local branches or tracking branches) or enters in an expression
in the expression input field we should automatically activate the
corresponding radio button for them.
