git-gui: Label the uncommitted blame history entry
If the user runs the blame viewer on a working directory file instead of a specific commit-ish then we have no value for the commit SHA1 or the summary line; this causes the history menu to get an empty entry at the very bottom. We now look for this odd case and call the meny entry "Working Directory". Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
