Nothing, i.e., there is no TERM in process-environment.  (I start
emacs from my .xinitrc so it will be available immediately---well, as
fast as emacs comes up, anyway.)

 Bart> Try this:

 Bart> 		    (format "COLUMNS=%d" (frame-width)))
 Bart> 	    (list "EMACS=t" "TERM=emacs"
 Bart> 		  (format "TERMCAP=emacs:co#%d:tc=unknown" (frame-width))))
 Bart> 	  process-environment)))
 Bart>     (apply 'start-process name buffer command switches)))

This also works.  (The previous solution was to add this:

   [[ $TERM = dumb ]] && unsetopt zle

to .zshrc.  Since you (Bart) are a lot more fluent in zsh stuff than I
am, could you comment on the relative merits of the two approaches?
