how can a definition-finding function tell which of the several
defvar's it may encounter.  AFAICT, there is no way for a
definition-finding function like tag-creation-function to tell which
is the 'defining' defvar and which is not...

but that's why i had an 'if' at the end.. to suggest that setq only if
not already defined.. else don't setq..
