[PATCH] gitk: Fix how remote branch names with / are drawn

[David Holmer <odinguru@gmail.com>]

Consider this example branch:

remotes/origin/master

gitk displays this branch with different background colors for each part:
"remotes/origin" in orange and "master" in green. The idea is to make it
visually easy to read the branch name separately from the remote name.

However this fails when given this example branch:

remotes/origin/foo/bar

gitk displays this branch with "remotes/origin/foo" in orange and "bar" in
green. This makes it hard to read the branch name "foo/bar". This is due
to an inappropriately greedy regexp. This patch provides a fix so the same
branch will now be displayed with "remotes/origin" in orange and "foo/bar"
in green.
