When commit shown is a merge commit (has more than one parent),
display combined difftree output (result of git-diff-tree -c).
Earlier (since commit 549ab4a30703012ff3a12b5455d319216805a8db)
difftree output (against first parent) was not printed for merges.
Examples of non-trivial merges:
5bac4a671907604b5fb4e24ff682d5b0e8431931 (includes rename)
addafaf92eeb86033da91323d0d3ad7a496dae83 (five parents)
95f97567c1887d77f3a46b42d8622c76414d964d (evil merge)

The same note as for the patch before apply: for trivial merges there
is no difftree output. But for 'commit' view it doesn't matter much
because there was no difftree output at all for merges.
I plan to add HTML diffstat (using divs with set background color and
set width for bar graph for diff stats) for merges for 'commit' view
(diffstat to first parent, aka. "damages"), and text diffstat for
'commitdiff_plain' view. It would be controlled by new %feature.
But if somebody else want to implement this, feel free.
Examples are included to make it possible to check combined diff
output in gitweb: the sha1 of commits should be turned into
hyperlinks (committags support), and you can click on them to go to
'commit' view.
