Split two error cases so they get reported distinctly.
If a macro is used with too few parameters, complaining about its
definition using '#' followed by something other than a macro
parameter name is apt to be confusing - reading the definition will
reveal that the name in fact is a macro parameter after all. The
reader needs attention directed to the invocation, not the definition.
Split the test in two: one to test the prior error message does in
fact get produced for an invalid macro definition, the other to test
the invalid invocation case.
