Does it matter?  I presume that a Porcelain that cares would
rather use the traditional "diff-tree -m -r" to look at diff
with each parent.  I dunno.

Yes, please preserve this behaviour.

Please _do not_ change this behaviour to make -m a no-op as stated in
"diff-tree -c raw output" patch message
(ee63802422af14e43eccce3c6dc4150a27ceb1a3).

The one you pulled already contains another one to fix that
ee6380 change done by gittus.  What "diff-tree -r -m ca1820"
shows should be the same as traditional "diff-tree -r -m ca1820"
output.

What is different is "diff-tree ca1820".  It used to show
*nothing* only because it is a merge.  It now defaults to show
"diff-tree -c ca1820".

For the sake of backward compatibility we could change it to not
output anything, but I sort of feel that is backwards.  If a
Porcelain wants raw-diff for 1 (or more) parents, "diff-tree -r
-m" has been the way to do so before the ee6380 change, and that
output has not changed (well ee6380 might have changed it but
now it is fixed).
