Subject: git-gui: Only allow Refresh in diff context menu when we have a diff.
X-Git-Tag: gitgui-0.6.0~58
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=86773d9bfc6124dec7b33094103f4819684bc4ae;p=git.git

git-gui: Only allow Refresh in diff context menu when we have a diff.

There is no reason to attempt refreshing an empty diff viewer, so
the Refresh option of our diff context menu should be disabled when
there is no diff currently shown.
