Broken MUAs, Pine and The Bat!

Here's a FWIW: after a bit more poking around, I've confirmed that
MUAs Pine on Linux and The Bat! on MSWindows confuse a long
series of dashes with the ^--boundary--$ string that is the end
of the digest.  I've submitted a bug report to the Pine folks
at the University of Washington, and maybe someday they'll fix it.
One of my digest readers has submitted a report to The Bat! folks.

In the meantime, I've added a workaround recipe to my digest's
rc.local.s10 file that should prevent those buggy mailers from
truncating my digests.
