I don't know about that bug ("command" works for me, but
my 4-stable is a few weeks older), but I'd suggest the
following definition of the shell function instead:
cd(){ chdir "$@" && PS1="`pwd`# ";}
chdir is simply a pre-defined alias for cd, so you can use
it inside that shell function safely without causing an
endless recursion. $@" is better than $* because it deals
with whitespace correctly.
