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.
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.
Also make *Help* links to ``' possible. Also make usable as such doc strings
on the function-documentation property of a symbol.
* lisp/emacs-lisp/backquote.el (top-level): Give , and '@ doc strings on the
function-documentation property. Also give these symbols a reader-construct
property.
* lisp/help-fns.el (describe-function): Allow the function-documentation
property to work. Use princ rather than prin1 to print the function's name
when it has a reader-construct property.
(help-fns-signature): Don't insert `high-usage' for a reader-construct.
(describe-function-1): Adapt to process documentation on the
function-documentation property. Print "a reader construct" when appropriate.
* lisp/help-mode.el (help-xref-symbol-regexp): Amend this regexp also to match
``'.
Problem reported by Artur Malabarba in:
http://lists.gnu.org/archive/html/emacs-devel/2015-11/msg01513.html
Most of these fixes are to documentation; many involve fixing
longstanding quoting glitches that are independent of the
recent substitute-command-keys changes. The changes to code are:
* lisp/cedet/mode-local.el (mode-local-augment-function-help)
(describe-mode-local-overload):
Substitute docstrings before displaying them.
* lisp/emacs-lisp/cl-macs.el (cl--transform-lambda):
Quote the generated docstring for later substitution.
Fixes: debbugs:19734
* lisp/emacs-lisp/backquote.el (backquote-delay-process): Don't reuse `s'
since it may be "equivalent" in some sense, yet different.
* test/automated/core-elisp-tests.el (core-elisp-tests-3-backquote): New test.
