Add full parser for git diff-tree output
The -c option to git log/diff-tree produces "merged" diffs with a
different format from normal ones. However, the existing diff-tree
parser only accepted non-merged diff lines. Merged diff lines caused
the parser to get out of sync. This patch adds a full parser for diffs
with any number of parents. See the "DIFF FORMAT FOR MERGES" section in
the git-diff-tree man page for more information.
