Btw, note the dramatic effect of this change on the results returned
by M-. for DEFVAR_LISP.

IOW, formerly src/TAGS would tell Emacs that all of this was the tag:

  DEFVAR_LISP ("pointer-make-invisible"

Which, of course, is incorrect, and caused a lot of false positives.

So the change to specify exactly where in the matched line is the tag
name was indeed in order, and the fact that \(..\) was used in the
regexp was a hint that it was intended.  If nothing else, the Emacs
manual explicitly advises to do so (which was how I became aware of
the feature in the first place).
