Not a command line flag but the command:

hg help env 

mentions the HGRCPATH environment variable. It is a typical :
separated path that tells hg where to look for its rc file. If it is
empty it reads only in the repository .hg/hgrc file and not in the
user's ~/.hgrc or anywhere else. So if vc-hg set HGRCPATH="" that
would fix the issue for me although someone who happens to put status
= -q in their repo/.hg/hgrc file would still encounter confusion. I
just have talked to the hg guys in #mercurial on freenode and they are
not aware of any way to completely disable all forms of hgrc reading.
