master with native compilation, if possible with --enable-checking.

My current theory is that one needs to C-h f a function with a doc
string lie this one:

(defun x-file-dialog (prompt dir &optional default-filename
                             mustmatch only-dir-p)
  "SKIP: real doc in xfns.c."
  (ns-read-file-name prompt dir mustmatch default-filename only-dir-p))

And the function must be native-comp-function-p.

I can't see so far how/where such "redirections" are handled.
