Also with a slight extension of diff part of 'commitdiff', by adding
line numbers for preimage in chunk and line numbers for postimage in
chunk, like e.g. in 'commit' view on GitHub[1] or on Gitorious[2] or
in SVN::Web[3] or in Atlassian FishEye, and adding anchors for those
line numbers we could go to given line in dif/patch output and examine
how it looked like before.

(This would probably require adding 'fmt' / 'format' parameter, where
one could choose between possible ways to view diff, or possible ways
to view log or log-like view.)


P.S. BTW. 'blame' view passes _original_ filename (not filename at
blamed commit) to 'commit' view link... but it doesn't matter because
'commit' view does not use 'f'/$file_name parameter.
