I looked at it and there are some small things you can do. First, you
should replace

  sub_hg = hg.repository(ui, path = subpath)

with

  ctx = repo['.'] # context for the working copy parent revision
  sub = ctx.sub(subpath) # subrepo for subpath

in order to create the right type of subrepository. We support both
Subversion and Mercurial subrepositories -- you will probably want to
test isinstance(sub, hgsubrepo) and act accordingly.

While your extension is definitely helpful, I'm planning something more
integrated, something that will allow me to do

  $ hg revert sub/a.txt

where the paths are crossing subrepository boundaries.

I've moved my patch repository here:

  http://hg.lazybytes.net/subrepos-mq/

and here you can see what I'm currently experiementing with for status:

  http://hg.lazybytes.net/subrepos-mq/file/tip/subrepo-status

It is just a prototype, I still don't know how to best integrate this
with the rest of Mercurial.
