repobrowse: linkify hunk headers

A work-in-progress, but this provides useful links to the
exact line number of modified lines instead of blindly linking
to the top-of-the-file.  Avoid flooding the user with links
but give hints by bolding the final resulting file or SHA-1
object ID.

Do other repository viewers do this?
