I was asking whether grouping by TAGS file is what the user might want
in this case, since, for example in Emacs, the distinction between
Lisp primitives implemented in C (and thus mentioned in src/TAGS), and
subroutines written in Lisp, does not necessarily exist.  Would the
users mind that, say, forward-line is separated from forward-paragraph?

I don't know the answer to that question, but I think it is worth
considering.
