Thank you for pointing that out. I fixed my misunderstood regexp. I would like to match the regexp with html or sgml comments like as much as possible. Please re-review it.

Sorry I've let this one slip, I've been terribly busy with other things in the past few weeks.

This still looks fishy to me. If I'm not mistaken, it would match all of the following as comments even though they aren't:

<!x-- ... -->
<!-- ... --x>
<!-- ... --->
<!-- ... -- ... -->

The last one might be tricky (or impossible) to cover with the regexp mechanics currently offered by dtrt-indent, so I think it would be OK to ignore it for now. But the first three can be done no problem as far as I can tell.

@jipodine, would you like to look at the outstanding issue on this pull request, and also rebase it?

[jipodine]

Good catch, but no time for this until next week...

Quick try, before disappearing for a while. Untested, sorry.
