Yes, you have a point, but...  Even though this is a bash list I still
prefer to use standard constructs when possible and practical.  Since
$PWD is a bash specific feature (would require #!/bin/bash) I would
still tend to use $(pwd) because that works both in bash and in POSIX
shells (would be okay with #!/bin/sh).
