Allow `auto-coding-functions` to know the file name.
Motivated by the needs of Editorconfig support.
* lisp/international/mule.el (auto-coding-file-name): New var.
(find-auto-coding): Let-bind it for `auto-coding-functions`.
Document the expectation that the arg be an absolute file name.
* doc/lispref/nonascii.texi (Default Coding Systems):
Mention `auto-coding-file-name`.
* test/lisp/international/mule-util-resources/test.utf-16le: New file.
* test/lisp/international/mule-tests.el (mule-tests--dir): New var.
(mule-tests--auto-coding): New fun.
(mule-tests--auto-coding-functions): New test.
* lisp/international/mule-cmds.el (ucs-names): Skip adding an old-name
if it conflicts with the offical name of a codepoint. Adjust the
ranges iterated over to account for new Unicode codepoints.
* test/lisp/international/mule-tests.el
(mule-cmds-tests--ucs-names-old-name-override,
mule-cmds-tests--ucs-names-missing-names): New tests for checking
'ucs-names' consistency.
Bug#65997
* test/lisp/international/mule-tests.el (sgml-html-meta-utf-8):
Accept also utf-8-unix/dos/whatever. (Bug#61534)
* lisp/international/mule.el
(sgml-html-meta-auto-coding-function): Fix comparison when
buffer-file-coding-system is of type 'charset'.
(dabbrev-expand-test, dabbrev-completion-test)
(dabbrev-completion-test-with-argument):
Use 'kbd' to format keys for 'execute-kbd-macro'.
(dabbrev-expand-test): Fix docstring.
* lisp/emacs-lisp/ert-x.el (ert-simulate-keys): New macro.
* test/lisp/international/mule-tests.el
(mule-cmds--test-universal-coding-system-argument): Use it and enable
the test also in batch mode.
* lisp/international/mule-conf.el (utf-7, utf-7-imap):
Add expedient to disable the :ascii-compatible-p property set
automatically by define-coding-system.
* test/lisp/international/mule-tests.el (mule-utf-7): New test.
(universal-coding-system-argument): Adjust the code to the way
`universal-argument` works nowadays. Handle `prefix-arg` a bit more
like `command_loop` does.
* test/lisp/international/mule-tests.el
(mule-cmds--test-universal-coding-system-argument): New test.
Don't bother with string-as-multibyte since `string` already returns
multibyte when needed. Don't forget to encode when the string is
ASCII, e.g. for ebcdic case and to make sure we always return
a unibyte string.
* test/lisp/international/mule-tests.el (mule-cmds-tests--encode-ebcdic):
New test.
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.
