TERM bug

[The Power Hungry <jszabo@xxxxxxxxxxxxxxxxx>]

If I start with TERM set to vt100, then change it to tty, then change it back
to vt100, the prompt loses it's escape sequences, and the RPROMPT is gone:

4:07am usacs ~/zsh-2.6-beta10 % TERM=tty                       [vt100] 07/07/95
4:07am usacs ~/zsh-2.6-beta10 % TERM=vt100
4:07am usacs ~/zsh-2.6-beta10 % exec -zsh
. .zshrc
  4:08am  up 85 days, 10:38,  6 users,  load average: 0.75, 0.48, 0.55
4:08am usacs ~/zsh-2.6-beta10 % fg                             [vt100] 07/07/95

You can't see it here, but at first usacs is bold and [vt100] is
reverse video.  The first is normal text and the second is gone after
TERM goes from vt100 to tty back to vt100.  It's gotten better though,
in older beta versions when you pressed return on a dumb terminal you
never got a new prompt.

I'm on a sun running sunos.  I'm not on the mailinglist, so please
reply by email.  Here is the output of reporter:
