sortcar and sort-subr

sortcar and sort-subr

[Stefan Monnier]

While adding a `predicate' argument to sort-subr, I noticed that
it uses a `sortcar' function (if fboundp) that I've never heard
of and that doesn't exist and seems never to have existed.

Any objection to removing it (and adding a `predicate' argument
for when your keys can't conveniently be numbers or strings) ?

Probably some remniscent of dynamic binding: use something like
(flet ((softcar some-function)) (sort-subr ...

Perhaps do a grep through other sources first to make sure it is
never used in that (ugly) manner.
