+Print a warning message when a global parameter is created in a function
+by an assignment.  This often indicates that a parameter has not been
+declared local when it should have been.  Parameters explicitly declared
+global from within a function using tt(typeset -g) do not cause a warning.
+Note that there is no warning when a local parameter is assigned to in
+a nested function, which may also indicate an error.
