Hi *,

related to my latest post (regarding hgrc handling):

When one works on an hg repository with an .hg/hgrc owned by someone
else, hg emits a warning like:

Not trusting file /home/foo/argh/.hg/hgrc from untrusted user foo, group foo

on stderr.[1]

Despite the warning hg still works as expected (ignoring the
repositories hgrc).  So ignoring the warning is TRTTD for Emacs.
Currently the warning text confuses vc, so that certain commands and the
revision display in the status bare don't work correctly.

The following patch achieves this by simply ignoring all output on
stderr for vc-hg-state and vc-hg-working-revision.

This might seem a little brute force, but its the most simple solution
and I believe it should be free of unwanted side effects:
