* lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): Before
going back a sexp from the \n marked with a string-fence syntax-table text
property, check that it is indeed a \n. If not, simply delete that text
property from the isolated quote, not the quote and the \n which otherwise
delimit an unterminated string. Should we encounter a double quote marked
with a string-fence syntax-table text property at the end of the last line,
remove that property.
* textmodes/bibtex.el (bibtex-reposition-window): New optional arg
pos.
(bibtex-search-crossref, bibtex-search-entry): Use it.
(bibtex-search-entry): If possible, reuse the window displaying

functions for supporting Imenu.

`imenu-prev-index-position-function', and
`imenu-extract-index-name-function'.

`css--extract-index-name' to support nested selectors.
* test/lisp/textmodes/css-mode-tests.el (css-test-current-defun-name):
Fix character index.
(css-test-join-nested-selectors): New tests for
`css--join-nested-selectors'.
* etc/NEWS: Add news entry.
* src/w32.c (g_b_init_reg_open_key_ex_w)
(g_b_init_reg_query_value_ex_w)
(g_b_init_expand_environment_strings_w): New init flags.
(globals_of_w32): Initialize them at startup.
(RegOpenKeyExW_Proc, RegQueryValueExW_Proc)

567cb9046d Overhaul pcase documentation
4d7e54acff Use EXPVAL in docstrings of patterns defined using pcase-d...
7e8227ed68 Introduce EXPVAL for pcase, pcase-defmacro docstrings
e6de5b3d51 Ensure pcase doc shows `QPAT first among extensions
* lisp/emacs-lisp/cl-print.el (cl-print--depth): New variable.
(cl-print-object) <cons>: Print ellipsis if printing depth greater
than 'print-level' or length of list greater than 'print-length'.
(cl-print-object) <vector>: Truncate printing with ellipsis if
vector is longer than 'print-length'.
(cl-print-object) <cl-structure-object>: Truncate printing with
ellipsis if structure has more slots than 'print-length'.
(cl-print-object) <:around>: Bind 'cl-print--depth'.
* test/lisp/emacs-lisp/cl-print-tests.el
(cl-print-tests-3, cl-print-tests-4): New tests.
This is needed to avoid losing user settings made under the obsolete
name (Bug#31603).
* lisp/epa.el (epa-pinentry-mode): Move obsolete varalias from here...
* lisp/epg-config.el (epg-pinentry-mode): ...to here.
Suggested by Drew Adams (Bug#31311).
* lisp/emacs-lisp/pcase.el (pcase): Use EXPVAL in
docstring to stand for the result of evaluating EXP.

ensures backquote is the first.
(Thanks to Stefan Monnier for improvements to this patch.)
* lisp/term.el (term--bash-needs-EMACS-status): New var.
(term--bash-needs-EMACSp): New function.
(term-exec-1): Use it instead of always setting EMACS.

(replace-tests--query-replace-undo, query-replace-undo-bug31073)
(query-replace-undo-bug31492, query-replace-undo-bug31538): Use it.
After previous commit, all tests using helper function
`replace-tests-clauses' fail: during the expansion
of macro `replace-tests-with-undo', the function
`replace-tests-clauses' is unbound.
Delete those helpers and reimplement test
`query-replace-undo-bug31538'.
* test/lisp/replace-tests.el (query-replace-undo-bug31538):
Reimplement this test without using any helper function/macro.
* lisp/replace.el (perform-replace): Update the replacement string
after the user edit it (Fix Bug#31538).
