unknown TERM problem.

unknown TERM problem.

[Tanaka Akira]

I found that unknown TERM causes core dump.

Z(2):akr@flux% TERM=xxx Src/zsh -f
zsh: can't find termcap info for xxx
flux% bindkey -e; autoload -U compinit; compinit -D
flux% zstyle ':completion:*:default' menu select=1
flux% ls <TAB><TAB>
CVS/zsh: segmentation fault (core dumped)  TERM=xxx Src/zsh -f
Z(2):akr@flux%

Actually, any terminal that doesn't have a programmable cursor will have
the same effect, e.g. TERM=dumb.

The following seems to be the correct fix; domenuselect() is a hook, so
there isn't any way to catch it before the function is entered.

This is dying at complist.c:1733 while trying to dereference p,
which is set to NULL because mmtabp is set to NULL, I think because
mtab is set to NULL, which may be because mnew is set to 0.

Or Bart could have fixed it already.

And all of that is because the complist module is expecting the complete
module (I think) to have created the completion listing before it gets
started, but the listing isn't created because the terminal can't do
cursor motions and hence can't handle alwayslastprompt.
