Don't you mean precmd?

Here's what I've got:

set prompt="%{\ek\e\\%}\%"

Note that the shell builtin "echo" and the set command both understand \e 
as echo, so we don't.

(man echo reveals that FreeBSD's echo doesn't support -e -- also, echo is 
probably being interpreted by tcsh's echo builtin)

Nope, gives me this:

\ekendif endif\e\\% for my first prompt (all other prompts are normal.)

What should I have my shelltitle set to?
