<snip useful suggestions>
These (and also that suggested by John in an earlier e-mail) still require a
change to /etc/profile. i.e. People with custom /etc/profiles will still need to
update them.

This one may work with bash, but I'm guessing the other shells aren't as
accomodating.

You've misunderstood me on this one. The csh profile.d file would require a {
if CHERE_INVOKING unset CHERE_INVOKING; else cd HOME }. This would be run for
login and non login shells. A login shell will then work as expected. A non
login shell (which doesn't normally cd HOME) would cd HOME. This can be worked
around, but why make trouble?
Anyway, I don't mind coming up with a more update (and maintainer) friendly way
for chere to get to the right directory, but I don't see that it's worth the
effort and pain of users having to change their profile again.
That said these modifications would take place in the base-files, zsh and tcsh
packages (and chere wouldn't change); so if John, Peter or Corinna want to
refactor things, that's OK with me.
Dave.
