subrepo: explicitly request clean and unknown files in status for git's add
No behavior changes here since gitsubrepo.status() doesn't currently populate
clean, and ignores whether unknown files were actually requested. But this is
in line with other calls to status, and should avoid future surprises.
Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:
http://docutils.sourceforge.net/rst.html
It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

Use the Makefile in this directory to generate the man and HTML pages.
