No, not in an sh shell. it does work, however, in the ksh shell.

The problem with this approach is that it will only be true for as long
as you stay in that directory.  in the example above for the ksh shell,
it will properly display the current directory no matter what directory
you move to.  there is no way that I'm aware of for it to be done in an
sh shell.  the csh shell allows it to be done using an alias on the cd
command, but this too will be broken if you decide to use chdir instead.
also, pushd, popd, and any other directory motion commands will break
csh prompts.

ksh seems to be the only one with the completely working approach.
