     this sets "stable" guard.  mq will skip foo.patch (because it has
     nagative match) but push bar.patch (because it has posative
-    match).  patch is pushed only if all posative guards match and no
+    match).  patch is pushed if any posative guards match and no
     nagative guards match.
 
     with no arguments, default is to print current active guards.
