diff format for merges
----------------------
"git-diff-tree" and "git-diff-files" can take '-c' or '--cc' option
to generate diff output also for merge commits. The output differs
from the format described above in the following way:
. there is a colon for each parent
. there are more "src" modes and "src" sha1
. status is concatenated status characters for each parent
. no optional "score" number
. single path, only for "dst"
Example:
------------------------------------------------
::100644 100644 100644 fabadb8... cc95eb0... 4866510... MM describe.c
------------------------------------------------
Note that 'combined diff' lists only files which were modified from
all parents.
