Still there is a problem how to specify which parts of replacement for committags have to be HTML escaped, and which are HTML and should not be (and which are attributes, and have to be escaped too).

Well, I think if it would be supported, it would be a very special case, so I don't think generic support for this is needed nor required. > > * Links to gitweb itself, such as 123abc:file.txt and HEAD:file.txt.

At this point I think we have already list of all references (for ref markers) so it wouldn't require additional call to git command. P.S. I understand that this post is an exception (send after long, long time), but please do not toppost in replies.
