I finally got around to checking the settings in the Makefile and
recompiling mutt.  End result: same problem.  If anyone else has any
ideas what might be causing this problem, please let me know.

addendum: The computer I'm using as a client to access mutt on another
machine doesn't have this same problem locally.  When I open a local mutt
instance, there's no junk on the screen.  I decided to try using SSH
through the remote system where I'm encountering this issue, then from
there using SSH to get back to the local machine, and opened mutt inside
this contrived SSH loop.  Still no problem.  Thus, whatever the problem
is seems to be particular to the remote machine.

I'm going to poke around some more and see if I can figure out what's up
while I wait for a response from anyone else who might have something to
offer, now that I've confirmed it seems to be specific to that machine.
Hopefully it's not related to the fact that the remote system is running
6.1-RELEASE while the system I'm using as a client is running
6.2-RELEASE, since that would pretty much mean I'm stuck with the
problem for quite some time (no desire to upgrade the FreeBSD version
number on the server).

I always wonder -- isn't the lemonade going to suck if life doesn't give
you any sugar?
