Default subjects like 'Re: Parent's subject' and a bit of code cleanup

I thought the consensus was that Re subjects were evil? "Re" serves to indicate which message replies to what in emails. With threaded support in mail clients that's now becoming obsolete too, but in Drupal I see no need whatsoever to imitate this bad practice.

This line:
$edit['subject'] = truncate_utf8(decode_entities(strip_tags(check_output($edit['comment'], $edit['format']))), 29, TRUE);

is the result of a long discussion about comment subject autogeneration. In light of various input formats, mandatory / disallowed subjects, this seemed like the best idea.

I think I want to +1 this, but I also think that the extra clutter in the web UI would be distracting. I think that comment titles should be optional -- and the email notifications that go out w/o a subject should grab the parent's subject like Drumm has done. So the real difference that I'm suggesting here is to allow for titleless comments, since people often write title-less comments anyway. Forcing a title only helps w/ email integration.

This should be somehow handled by listhandler. Preferably by educating users to use proper MUAs which acn do threading without Re:s in subjects.

When in doubt use a bigger club.

Or get a consultant to implement your feature wishes. Done. Will be uplaoded later today.
