'hg status -q' output skips non-tracked files. The '-q' flag was ignored in status command. But this flag can be used to hide non-tracked files in hg status output. This small correction makes status command more general, similar to 'svn status', where '-q' flag has the same effect. The '-u' and '-A' flags have priority over '-q'. A testcase and doc-string for status was extended to cover '-q' flag.
