What's wrong:
Viewing a message which contains a base64 encoded zip archive disguised
as text/plain results in caracters cat'd to my terminal which trash it.
Please describe any relevant documentation references:
My $PAGER and showproc (in .mh_profile) are both set to "less".

I suspect there's nothing special about my peice of spam that triggered
it, but I'd be happy to provide it in entierity, if that's useful.
