gitweb: Use parse_difftree_raw_line in git_difftree_body
authorJakub Narebski <jnareb@gmail.com>

Use newly introduced parse_difftree_raw_line function in the
git_difftree_body subroutine.  While at it correct error in
parse_difftree_raw_line (unquote is unprototyped function), and
add comment explaining this function.

It also refactors git_difftree_body somewhat, and tries to fit
it in 80 columns.
