* lisp/ielm.el (inferior-emacs-lisp-mode): Add
`elisp-eldoc-var-docstring' and `elisp-eldoc-funcall' as
`eldoc-documentation-functions' instead of the undefined
elisp-eldoc-documentation-function (bug#42493).

(eldoc--eval-expression-setup): Use new hook.
(eldoc--supported-p): Accomodate new hook.

functions.

default value. Update documentation and custom attributes.

'eldoc-documentation-function'.

new hook and changes to 'eldoc-documentation-function'.

directives instead of real variable definitions to avoid polluting
the global Emacs namespace.
(*1, *2, *3): Ditto.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
* lisp/startup.el (command-line): Default to lexical-binding in *scratch*.
(normal-no-mouse-startup-screen, command-line-1):
Use startup--get-buffer-create-scratch.
(command-line-1):
* lisp/simple.el (eval-expression):
* lisp/server.el (server-eval-and-print): Use lexical-binding to
evaluate the expression.
(server-execute): Use startup--get-buffer-create-scratch.
* lisp/ielm.el (inferior-emacs-lisp-mode): Default to lexical-binding.
The ielm buffer name was hardcoded which made it hard for programs to
interactively create ielm buffers with different names and switch to
them (e.g. perhaps you want to have one ielm buffer for each of the
Elisp projects you're working on).
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

command names and the last command. Always display additional
formats of the integer result in the echo area, and insert them
to the current buffer only with a zero prefix arg.
Display character when char-displayable-p is non-nil.
(eval-expression): With a zero prefix arg, set `print-length' and
`print-level' to nil, and insert the integer values from
`eval-expression-print-format' at the end. Doc fix.
* lisp/emacs-lisp/lisp-mode.el (eval-print-last-sexp): Add arg
`eval-last-sexp-arg-internal'. Doc fix.

comint-dynamic-complete-functions.
