How do you envision a backward-compatible extension of TAGS format to
support such flags? AFAIK, TAGS doesn't distinguish between the tags
by their kind, it just records all of them, and leaves the semantics
to the program which reads them. The current format of TAGS is
described in etc/ETAGS.EBNF, in case you didn't know.
