Subject: [PATCH] Avoid external "/bin/pwd"

.. as it may not be available everywhere, see #1521 (NixOS).

This commit replaces all instances from pwd or /bin/pwd by $PWD.
It is a bash internal and the fastest. Also it added some quotes
to PWD a it may contain white spaces in the future (currently
there's a check for it that it won't)
