* lisp/net/eww.el (eww-readable-urls): New option.
(eww-default-readable-p): New function...
(eww-display-html): ... use it.

* test/lisp/net/eww-tests.el (eww-test/readable/default-readable): New
test.

* doc/misc/eww.texi (Basics): Document 'eww-readable-urls'.

* etc/NEWS: Announce this change (bug#68254).

Additionally, add an option to prevent adding a new history entry for
each call of 'eww-readable' (bug#68254).

* lisp/net/eww.el (eww-retrieve):

* lisp/net/eww.el (eww-readable-adds-to-history): New option.
(eww-retrieve): Make sure we call CALLBACK in all configurations.
(eww-render): Simplify how to pass encoding.
(eww--parse-html-region, eww-display-document): New functions, extracted
from...
(eww-display-html): ... here.
(eww-document-base): New function.
(eww-readable): Toggle "readable" mode interactively, like with a minor
mode.  Consult 'eww-readable-adds-to-history'.
(eww-reload): Use 'eshell-display-document'.

* test/lisp/net/eww-tests.el (eww-test--with-mock-retrieve): Fix indent.
(eww-test/display/html, eww-test/readable/toggle-display): New tests.

* doc/misc/eww.texi (Basics): Describe the new behavior.

* etc/NEWS: Announce this change.

The 'shr-fill-...' functions handle both hard-filling (adding
newlines to break long lines) and indentation.  Setting
'shr-fill-text' to nil currently causes these functions to be
short-circuited completely, so e.g. blockquotes are no longer
indented, whereas the intent of this user option is only to
prevent hard-filling to let visual-line-mode reflow text.

* lisp/net/shr.el (shr-fill-lines): Document that the function
handles more than just filling; move the 'shr-fill-text' check...
(shr-fill-line): ... here, after indentation has been taken care
of.
* test/lisp/net/shr-resources/blockquote.html:
* test/lisp/net/shr-resources/blockquote.txt: New test resources.
* test/lisp/net/shr-tests.el (shr-test--rendering-check): Rename
from 'shr-test', to make the relationship with the 'rendering'
testcase clearer; prefer 'file-name-concat' to 'format'; raise
ERT failure if need be, calling (ert-fail ...) directly instead
of (should (not (list ...))).
(shr-test--rendering-extra-configs): New variable to easily check
that user customizations do not degrade rendering.
(rendering): Consult that new variable; delegate failure-raising
to reduce duplication.

This resolves an issue where navigating back and then forward kept
adding new history entries so you could never hit the "end" (bug#69232).

* lisp/net/eww.el (eww-before-browse-history-function): New option.
(eww-history-position): Add docstring.
(eww-mode-map, eww-context-menu): Use correct predicates for when to
enable back/forward.
(eww-save-history): Save history entry in its original place when
viewing a historical page.
(eww--before-browse): New function...
(eww, eww-follow-link, eww-readable): ... call it.
(eww-render): Don't set 'eww-history-position' here...
(eww--before-browse): ... instead, set it here.
(eww-back-url): Set 'eww-history-position' based on the result of
'eww-save-history'.
(eww-forward-url): Set 'eww-history-position' directly, since
'eww-save-history' no longer adds a new entry in this case.
(eww-delete-future-history, eww-clone-previous-history): New functions.

* test/lisp/net/eww-tests.el: New file.

* etc/NEWS: Announce this change.

* doc/misc/tramp.texi (External methods):  Add dockercp and podmancp.

* etc/NEWS: Add Tramp methods "dockercp" and "podmancp".

for "dockercp" and "podmancp" completion.

* lisp/net/tramp-gvfs.el (tramp-gvfs-maybe-open-connection):
* lisp/net/tramp-sh.el (tramp-maybe-open-connection): Use a default
value with `tramp-get-method-parameter'.

(tramp-default-copy-file-name): New defconst.
(tramp-make-copy-file-name): Rename from
`tramp-make-copy-program-file-name'.  Use method parameter
`tramp-copy-file-name'.  (Bug#69085)
(tramp-do-copy-or-rename-file-out-of-band): Adapt callees.

* lisp/net/tramp.el (tramp-methods): Adapt docstring.

argument DEFAULT.

* test/lisp/emacs-lisp/macroexp-resources/vk.el (vk-b):
Don't use `defconst` if it's not constant.
