Well, surprise, surprise.  The file does have CR-LF line endings,
and stripping out the CRs seems to make the problem go away.

We imported the mailbox data from our old mail servers which were
FreeBSD boxes running a really old version of Cyrus.  For some reason
the messages in users' Cyrus mailboxes had CR-LF instead of the
standard Unix LF line endings.  Wacky.

Anyway, thanks for the pointers on this.  I'm happy that it turned
out to be something mundane and easily fixable, even though we've
burned a bunch of time beating our heads against the issue.
