This isn't really on-topic for mercurial-devel. You should really ask
on the mercurial users list, or on any of the Mozilla-specific hg
forums that are out there (I hang out in #hg on irc.mozilla.org, for
example; there are probably relevant newsgroups as well).

That said, many bugs will have a final comment with a link to the
pushed cset, where you could get the changeset. Iterating over the
changelog and reading the commit message is another good option;
almost every commit should have a bug id in it.

The easiest way to compare the diffs might be to run hg diff -c
<cset-id> on a local clone to get the changeset diff, then compare
that to the diff from the attachment (you could run diff on the diffs,
which might actually be useful in this case, though diffs of diffs are
somewhat hard to read).

Cheers,
