files: don't recurse into subrepos without a path or -S (issue5127) The 'm.always()' check was needed for when a path to 'sub1' is given, and 'sub1' contains a subrepo itself. But that also caused the automatic recursion when no path was given. Instead, force -S when printing a subrepo if the subpath is an exact match (which will unconditionally recurse once in the nested subrepo).
