`hg status` did not add outside.

Unfortunately this is not really a candidate for adding to narrowhg proper,
since it depends on some other source for providing the manifests (when using
treemanifests) and file contents. Something like a virtual filesystem and/or
remotefilelog. We want to be useful when not using those systems, so we do not
have this method available in narrowhg proper at the moment.

Since we do not have the ability to rely on a virtual filesystem or
remotefilelog in the test, we just fake it by copying the data from the 'master'
repo.
  $ cp -a ../master/.hg/store/data/* .hg/store/data
Do that for patchdir as well.
  $ cp -a ../master/patchdir .

`hg status` will now add outside, but not patchdir.
  $ DIRSTATEINCLUDES=path:outside hg status
  M outside/f2
  $ hg tracked | grep outside
  I path:outside
  $ hg files | grep outside > /dev/null
  $ hg tracked | grep patchdir
  [1]
  $ hg files | grep patchdir
  [1]

Get rid of the modification to outside/f2.
  $ hg update -C .

This patch will not apply cleanly at the moment, so `hg import` will break

Let's make it apply cleanly and see that it *did* expand properly
