Well as I have metioned earlier, IMHO which is from tcsh, so the correct
behaviour is what tcsh does. However I realise that different implementations
of tcsh might have different behaviour, so this might not solve the problem.

This is what happens at work, on a SUN running Solaris:
mpw wtree 78 > which ls cat
ls:      aliased to ls -F
/usr/bin/cat
mpw wtree 79 > which arne
arne: Command not found.
