* lisp/isearch.el (isearch-beginning-of-buffer)
(isearch-end-of-buffer): Fix their behavior when
isearch-repeat-on-direction-change is non-nil (bug#50466).
* lisp/isearch.el (search-whitespace-regexp): Change the default
to always exclude newlines from the set (bug#21278). It used to
be mode-dependent whether newlines were included or not, and this
was confusing as a user interface.
* lisp/progmodes/etags.el (xref-etags-apropos-location):
New class.
(xref-location-marker): New method definition.
(xref-make-etags-apropos-location): New function.
(etags--xref-apropos-additional): New function.
(xref-backend-apropos): Use it here.
* etc/NEWS: Improve wording of tab-bar related entries.
* lisp/tab-bar.el (tab-bar-show, tab-bar-select-tab-modifiers):
Improve and clarify the doc strings.
* lisp/progmodes/python.el (python-shell-send-string): Only heed
'comint-max-line-length' for subprocesses with which we
communicate via PTYs. (Bug#49822)
* lisp/comint.el (comint-max-line-length): Doc fix. Add a value
for MS-Windows.
* lisp/progmodes/ruby-mode.el (ruby-smie-rules): Align with the
first sibling on the previous line instead of the last (bug#32496).
That is, before it used to be
one.two.three
.four
and now it is
one.two.three
.four
* lisp/comint.el (comint-max-line-length): New constant reflecting a
safe maximum line size that can be sent to an inferior process.
* lisp/progmodes/python.el
(python-shell-comint-watch-for-first-prompt-output-filter): Send setup
code to the inferior process only once and at this stage.
(python-shell-eval-setup-code, python-shell-eval-file-setup-code):
Move, unchanged, to an earlier point to avoid byte-compiler warnings.
(python-shell-send-string-no-output): Revert changes of e32c7d2a8d
(python-shell-send-string): Use 'comint-max-line-length' to decide
when to resort to temp files.
(python-shell-send-string, python-shell-send-file): Don't send setup
code each time (bug#49822).
* lisp/simple.el (pop-mark): Don't ding at the user if there's no
mark to pop (bug#44375). This function is used (in some
circumstances) when the user mouse-1-clicks links (in *Help*
buffer, for instance), which will then ding at the user before
following the link.
* lisp/progmodes/python.el
(python-shell-completion-native-disabled-interpreters): Remove
ipython from list, because it apparently works fine these days
(bug#50458).
* lisp/help-fns.el (help-fns--customize-variable-version):
Factored out from `help-fns--customize-variable' to be able to see
whether it outputs anything.
(help-fns--run-describe-functions): New function.
(help-fns--activated-functions): New internal variable.
(describe-variable): Use new function.
(describe-face, describe-function-1): Ditto (bug#50463).
Following advice by Mattias Engdegård, most uses of rx-to-string
were eliminated, and rx sequences used instead to define Perl
grammar components.
* lisp/progmodes/cperl-mode.el: (cperl-block-declaration-p): New
function, replaces regexp literals.
(cperl-imenu--function-name-regexp-perl): Deleted, use rx
sequences to find imenu entries instead.
(cperl-indent-line): Use rx components instead of regexp literals.
(cperl-sniff-for-indent): use `cperl-block-declaration-p' to
increase accuracy, use rx sequence for labels to replace
inaccurate regexp literals.
(cperl-block-p): Replace inline comment by docstring. Use
`cperl-block-declaration-p'.
(cperl-after-block-p): Use `cperl-block-declaration-p'.
(cperl-after-block-and-statement-beg): Replace inline comment by
docstring.
(cperl-imenu-package-keywords), (cperl-imenu-sub-keywords),
(cperl-imenu-pod-keywords) : New variables to sort imenu
entries into categories.
(cperl-imenu--create-perl-index): Use rx sequences to collect
imenu entries.
(cperl-init-faces): Use rx components instead of regexp literals
for labels.
* test/lisp/progmodes/cperl-mode-tests.el: Test rx sequences
instead of regexp strings
* lisp/gnus/nndiary.el (nndiary-open-server): Move the manipulation of
`gnus-extra-headers' and `nnmail-extra-headers' into this function: it
should only happen if we're actually firing up an nndiary server.
Previously, simply attempting to complete a gnus-* prefixed symbol
could end up loading this file, and changing the variable values.
* lisp/net/browse-url.el (browse-url-default-windows-browser)
(browse-url-default-macosx-browser): Encode the URL before using
(in case it contains spaces) (bug#50435).
* lisp/net/browse-url.el (browse-url-url-encode-chars): Document
what the argument really is, and simplify the implementation
(bug#50435).
(browse-url-encode-url): Encode spaces.
* lisp/progmodes/xref.el (xref-auto-jump-to-first-definition)
(xref-auto-jump-to-first-xref): More accurate description in the
doc strings.
* doc/emacs/maintaining.texi (Looking Up Identifiers)
(Identifier Search, List Identifiers, Project File Commands): Fix
the documentation of 'xref-auto-jump-to-first-definition' and
'xref-auto-jump-to-first-xref' to be more accurate.
* etc/NEWS: More accurate wording of the entry about
'xref-auto-jump-to-first-definition' and
'xref-auto-jump-to-first-xref'.
* lisp/net/tramp.el (tramp-completion-handle-file-name-all-completions):
Do not expand default method, user, host. (Bug#50387)
(tramp-get-completion-methods): `partial-method' can be nil.
