Do I understand correctly that this command definition, as well as
others you added in this patch, makes the command use the default
completion function?  If so, I'm not sure that's a good idea, unless
the tables scanned by make_symbol_completion_list store macro names.

It would be nice to have completion only on macro names in these
commands.  But if that cannot be done easily, at least let's disable
completion entirely until something appropriate is coded.
