Integrating Matt Palmer's patch to provide a 'plugins'

mount, fixing #891.  The patch was ported to the current
code by David Schmitt, I applied the rest of Matt's
patches, and I then fixed all of the code so that the
tests passed.

The primary change I had to make to the patch was reenabling
host expansion in paths -- his patch had disabled it.
