I'm sure I'm going about this the wrong way, but at least it seems to work ...

My problem is that I'm using a value of $TERM that's not present in the
system's terminfo database, so when zsh starts up, its terminal handling is
pretty confused.

I'd like to be able to set TERMINFO to the proper path, but in order for
that to do anything, the terminal needs to be reinitialized.  So I've made
TERMINFO a special variable that calls init_term() when it's set, and it
seems to work okay.  I'm guessing that the addenv() call isn't necessary,
but I can't figure out how it ought to work.
