* lisp/subr.el (provided-mode-derived-p): Remove detail about "or
their aliases", since that seems self-evident (bug#46331) (and
derived-mode-p works the same, and doesn't have the bit in
question).
* lisp/gnus/message.el (message-send): Query if it looks like
encryption was intended, but is not going to happen.
* lisp/gnus/mml-sec.el (mml-secure-is-encrypted-p): Allow saying
whether there's any <#secure tags present (bug#24411).
* lisp/emacs-lisp/testcover.el: Rename the symbol `1value'
throughout the file to `testcover-1value' to allow using the
variable in code that's to be tested (bug#25471).
* lisp/subr.el (provided-mode-derived-p): Allow this to work on
modes that are aliases of other modes (bug#46331). For instance:
(provided-mode-derived-p 'javascript-mode 'prog-mode)
* lisp/auth-source.el (auth-source-search): Adapt docstring
(auth-source-format-prompt): Remove trailing ": ".
(auth-source-netrc-create, auth-source-secrets-create)
(auth-source-plstore-create): Adapt prompts. Use `format-prompt'.
Do not ask interactively if `auth-source-save-behavior' is nil.
* src/editfns.c (styled_format): Fix accounting for text
properties that come from the format string. (Bug#46317)
* test/src/editfns-tests.el (format-properties): Add new tests for
bug#46317.
* src/xdisp.c (Fwindow_text_pixel_size): Fix last change: preserve
the original Y coordinate after start_display, instead of zeroing
it out. Reported by martin rudalics <rudalics@gmx.at>.
* doc/lispref/syntax.texi (Syntax Properties): Correct the
information about flushing the state by copying the text from the
doc string (bug#46274).
(cherry picked from commit ff701ce2b2)
* doc/emacs/indent.texi (Indentation Commands): Clarify that the
other keys don't just exit the transient mode, but are also
handled as normally (bug#46296).
* lisp/term.el (term-emulate-terminal): Ensure that the buffer is
still alive before selecting it (bug#46323). This avoids an error
when saying `C-x k' in an ansi-term buffer.
* lisp/progmodes/project.el (project-find-regexp):
Fix the previous change (project-root is not defined in this version).
(project-or-external-find-regexp): Same.
* lisp/progmodes/project.el (project-find-regexp):
Bind default-directory to the project root, to save this value
in the resulting buffer (esp. if the project selector was used,
(https://lists.gnu.org/archive/html/emacs-devel/2021-02/msg00140.html).
(project-or-external-find-regexp): Same.
(cherry picked from commit c07ebfcbe0)
* src/lread.c (Fread_char, Fread_event, Fread_char_exclusive):
Call cancel_echoing to make sure the prompt is not obscured by
keystrokes echo. (Bug#46243)
* lisp/progmodes/python.el (python-shell-send-region): Deactivate
mark after executing (bug#28789). This is how this command worked
in Emacs 24, apparently.
* src/xdisp.c (Fwindow_text_pixel_size): Support the use case
where FROM and TO belong to the same screen line. Reported by
Yuan Fu <casouri@gmail.com>.
* doc/lispref/modes.texi (Defining Minor Modes): Document it.
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Allow specifying a :variable to be used if the underlying mode has
a divergent variable to store the state (bug#29081).
* lisp/ibuffer.el (recency): Remove.
(recency): New macro function so that sorting by recency is
stable when inverted sorting is switched on (bug#30129).
