'$' signs in messages

$strings in messages are not being archived, and instead, are being
stripped from the resultant message.  For example a message body
which reads in part:

--<cut>--
  All newly created objects inherit by default from $NEW_OBJECT
--<cut>--

will archive as

--<cut>--
  All newly created objects inherit by default from
--<cut>--

How to fix?

$ mhonarc -v
  MHonArc v2.4.8 (Perl 5.006001)
