bug#45197: Saving customizations makes ~/.config/emacs/init (no .el extension)

[tsuucat]

                  (unless init-file-name
                    (setq init-file-name alt-file))
is added
in 
https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=4118297ae2fab4886b20d193ba511a229637aea3.

Before this commit, I think ‘.emacs’ is always used  for ‘user-init-file’ value 
if
init file is missing.

                 (and (equal (file-name-extension alt-file) "el")
                      (setq alt-file (file-name-sans-extension alt-file)))
...
                 (load alt-file 'noerror 'nomessage)))

should be also changed in the commit to use “init.el” not “init".

I can’t find such a code.

I made a patch to set 'user-init-file' value to init”.el" for XDG convention 
users 
who do not have an init file.

(But alternate-filename-function is only used for "init.el” so 
                  ...(if (equal (file-name-extension alt-file)
                                 "el")
                            (file-name-sans-extension alt-file)
                          alt-file)...
may be redundant.)
