* src/fileio.c (Fdirectory_append): Change the function to take an
arbitrary number of components.
* lisp/simple.el (separator-line): Tweak definition to not be so
overwhelming.
* lisp/emacs-lisp/shortdoc.el (shortdoc-separator): Removed.
(shortdoc-display-group): Use make-separator-line.
* lisp/emacs-lisp/shortdoc.el (shortdoc--goto-section): Adjust to
changes in how the text properties are inserted in 22a5482ab6
(bug#49605). Also make into a regular function.

the shortdoc buffer.
* lisp/emacs-lisp/shortdoc.el (shortdoc-add-function): Use nconc to
actually append a new section to the list of groups while avoiding a
previous OBOE. Push a new group to the front of shortdoc--groups
without copying it, just like define-short-documentation-group does.
(buffer): Fix copypasta in unlock-buffer example.
* test/lisp/emacs-lisp/shortdoc-tests.el (shortdoc-examples): Also
check that :no-value forms demonstrate the right function.
* doc/lispref/help.texi (Documentation Groups): Clarify that @dots
in the define-short-documentation-group arglist refer to whole
key-value pairs. Fix typo in :eg-result-string description.

example.
* lisp/emacs-lisp/shortdoc.el (define-short-documentation-group): Add
:no-eval* and :result-string keywords to the docstring. (Bug#48730)
Make sure that each example in shortdoc actually contains the function
it illustrates, and add a test for it.
* lisp/emacs-lisp/shortdoc.el (string, list, buffer, number):
Use the right functions in examples for string-version-lessp,
lax-plist-put, point-min and ffloor.
* test/lisp/emacs-lisp/shortdoc-tests.el: New test file.
* shortdoc.el (shortdoc-heading): Define new face for headings.
(shortdoc-display-group): Apply new heading face.
(shortdoc--display-function): Use existing face for section text.
* etc/NEWS: Document new face (bug#46748).
* lisp/emacs-lisp/shortdoc.el (shortdoc--display-function): Use
describe-function as a fallback link when a function is not documented
in any Info manual. Also make the link respond to mouse-1, like the
rest of *Help* links, and add a proper help-echo property.
* lisp/help-fns.el (help-fns--mention-shortdoc-groups): Same link
improvement as described before, this time for the shortdoc groups
(bug#45750).

(length_internal): New function.

* lisp/emacs-lisp/shortdoc.el (shortdoc-example): Removed.
(shortdoc-section): Remove colors.
(shortdoc-separator): New face.
(shortdoc-display-group, shortdoc--display-function): Don't use
background colours, because that makes things harder to read.
