+    [partial cherry-pick] 51573: additional "typset -p -m" fix for namespaces
+    
+    The "-m pattern" option is supposed to enable printing namespaces, but
+    that didn't work when combined with -p.
+    
+    The -p option could also cause an unset parameter to become set if a
+    named reference pointed at it.
