Thanks for the pointers. In particular:
compgen -c | sort -ui | dmenu.xft -fn 'Lucida-12'
works quite well, and on a fast machine, there isn't any lag in
generating that list on the fly with compgen.
compgen, BTW, is interesting, and the only complaint I have is that that
invocation includes shell builtins, such as "[[", and I'm not sure how
best to filter those out. Even a regex calling for "starts with class
alphanumeric" wouldn't get rid of all the builtins.
