The function name is right, but its contents is not too right.

Currently there are different methods for obtaining an identifier
at point:

- `find-tag-default' and `find-tag-default-function' from etags.el

- `symbol-at-point' from thingatpt.el

- info-look.el which has the most advanced implementation since
  it defines regular expressions and parsing rules for guessing
  the default identifier for 20 major modes (and one special
  function `info-lookup-guess-c-symbol' for C mode).

So to create right contents of `identifier-at-point' these packages
could be generalized.

Anyway, we could install this function now as a general method
to get an identifier at point, with the identifier guessing method
from etags.el, and improve its contents later.
