[PATCH 3/4] gitweb: Extend parse_difftree_raw_line to save commit info

[Jakub Narebski <jnareb@gmail.com>]

Extend parse_difftree_raw_line to save commit info from when
git-diff-tree is given only one <tree-ish>, for example when fed
from git-rev-list using --stdin option.

git-diff-tree outputs a line with the commit ID when applicable.

This can be applied regardless that it is proof-of-concept series.
Need checking if it doesn't break anything.
