I think this sounds like an interesting and useful feature.

I think it would be better to let the user specify the narrow path in
the .hgsub file and reserve the .hgsubstate file for Mercurial. I'm
imagining a format like this:

  path = [type, param1: value1, param2: "value2 with spaces", ...] url

in the .hgsub file. I guess we can adapt ui.configlist to handle this,
if we decide to to with this format.
