Subject: gitk: Disable the head context menu entries for the checked-out branch
X-Git-Tag: v1.5.3-rc0~49^2~12
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=00609463979c3a2549c0c917a206345f51975b5d;p=git-core%2Fgit.git

gitk: Disable the head context menu entries for the checked-out branch

Neither the "check out this branch" nor the "remove this branch"
menu item can be used on the currently-checked out branch, so disable
them.
