Subject: [PATCH] gitk: Add "Refs" menu - revised
Message-ID: <1128571883.32103.48.camel@dv>
In-Reply-To: <1128559088.32103.8.camel@dv>

Hello!

This is an updated revision of the original patch.  Unneeded concat has
been removed.  Error message uses name, not SHA1 ID.  If there is
information for the tag, it's displayed even in the ID is not in the
list.  Thanks to Brett Schwarz for help.

---------------------------------

This patch adds "Refs" menu to gitk.  It makes all branches, tags and
other ref objects appear as menu items.  Selecting one of the items
selects the corresponding line in the view.

It's only possible to go to the refs present in the current view.
However, information for tags is shown even if the corresponding ID is
not available.
