Eww. yuck.  I personally believed that patchworks should not only keep all the
comments posted to a mailing list but keep them as read only.  And then
use the Patch class as a workspace (using one of the Comments as a
template).  This would allow maintainers to muck around with the patch as
they see fit for their workflow, but still have the original thread if
they need it.

Destroying Comment 0 now creates two types of data in patchworks, replies
and patches.  What happens when patchwork accidentally labels a reply with
a patch snippet as a Patch?  How do you take that Patch turn it into a
Comment and link it to the appropriate Patch?  It gets kinda messy.

If you treat all the threads as Comments and then Patches as special case
Comments, then moving things around is very simple.  For example
connecting superceded patches together is just a matter of modifying the
patch_ids to point to the new patch and viola you have the full history of
a the patch (well you lose the original patch because patchworks doesn't
have a field in the Comments class for patch_contents).

Just my two cents.
