Only read .hg/hgrc files from trusted users/groups The list of trusted users and groups is specified in the [trusted] section of a hgrc; the current user is always trusted; "*" can be used to trust all users/groups. Global hgrc files are always read. On Windows (and other systems that don't have the pwd and grp modules), all .hg/hgrc files are read. This is essentially the same patch that was previously applied as revision 494521a3f142.
