If anyone is curious, the patch to enable this is small and looks
something like the below.  Exporting some additional variables might
be helpful at some point, this is really just a (working) proof of
concept.

I've tested the below with a trival script that just printed a few
lines of output to announce that it had been called.

This could allow the core of pass to remain small and allow extension
scripts to be called transparently.  One detractor from this approach
is that info about extension scripts would not appear in pass' usage
info.


Note:  not git formatted, as this is just an idea for discussion at this point.
