In fact I got that loop at some point when writing the function
and switched to precmd so that I don't have to think about it.

That's how I've been doing it for ages to set the xterm title.

Nope, I'm still using the zsh that came with SuSE 7.1 at work (3.1.9).

I can't use this approach because there are some directories on
the share that are not remapped to /.  Some are mapped to named
directories that not necessarily have the same name (obviously, I
can't give the tmp directory on the share the name 'tmp').
