Subject: git-gui: Display both commits in our tooltips
X-Git-Tag: gitgui-0.7.3~5
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=383d4e0f8b72f739c16ef7d723a134d59a0a0c2f;p=git.git

git-gui: Display both commits in our tooltips

If we have commit data from both the simple blame and the
rename/move tracking blame and they differ than there is a
bigger story to tell.  We now include data from both commits
so that the user can see that this link as moved, who moved
it, and where it originated from.
