throughout.
* doc/emacs/package.texi (Package Installation): Document this.

* doc/lispref/package.texi (Package Archives): Don't document
package-x upload functions in the elisp manual, since they are not
very commonly used. (Bug#19537)

* lisp/gnus/gnus-sum.el (gnus-shorten-url): New function.
(gnus-summary-browse-url): Change function to make `C-u' use the
external browser (as Gnus does when you hit URLs manually). Don't
use an initial input.
* doc/misc/efaq.texi (No Escape key):
* doc/emacs/msdos-xtra.texi (MS-DOS Keyboard): Change back to
function-key-map from local-function-key-map, because these
bindings apply to all terminals.
* doc/lispref/keymaps.texi (Translation Keymaps): Clarify in what
circumstances you may still want to use function-key-map.
Derived from Ken Brown’s patch (Bug#36502#97).
* doc/lispref/files.texi (Relative File Names):
* etc/NEWS: Document this.
* src/fileio.c (user_homedir): New function.
(Fexpand_file_name, file_name_absolute_p): Use it.
(search_embedded_absfilename): Simplify via file_name_absolute_p.
* test/src/fileio-tests.el (fileio-tests--no-such-user): New test.
* doc/misc/edt.texi (Changes):
* doc/emacs/custom.texi (Terminal Init): Use input-decode-map
instead of local-function-key-map, according to Stefan Monnier.
* doc/emacs/search.texi (Lax Search): Document
char-fold-symmetric, char-fold-include, char-fold-exclude.
* lisp/char-fold.el (char-fold--default-include)

* doc/misc/viper.texi (Key Bindings):
* doc/misc/efaq.texi (X key translations for Emacs)
(No Escape key):
* doc/misc/edt.texi (Changes):
* doc/emacs/msdos-xtra.texi (MS-DOS Keyboard):
* doc/emacs/custom.texi (Terminal Init): Refer to
local-function-key-map instead of function-key-map, since the
latter isn't supposed to be changed (bug#27490).
Say that pdumping cannot redump unless -batch is used. Say that
the traditional unexec dumping method is by default not available,
and is deprecated. Don't call dump files "portable", as dump files
are not any more portable than the Emacs executables themselves.
Just call them "dump files". Similar, prefer "portable dumper"
(since the dumper code is portable) to "portable dumping" (since
the dump file is not). Be more systematic about calling them
"dump files" instead of "dumped images" or whatnot.
* doc/lispref/strings.texi (Formatting Strings): Document this.
* src/editfns.c (styled_format): Support %o, %x, and %X on
finite floats less than zero or greater than UINTMAX_MAX.
* test/src/editfns-tests.el (format-%x-large-float)
(read-large-integer, format-%o-negative-float):
Adjust tests to match extended behavior.
Rename the latter test from format-%o-invalid-float,
since the float is no longer invalid.
* test/src/editfns-tests.el (format-%x-large-float)
(read-large-integer): Test this.

Don’t insist that hash codes be fixnums, reverting
the recent doc changes to the contrary.
* src/bytecode.c (exec_byte_code): Special-case only the eq case,
as the others aren’t worth tuning now that we treat bignum hashes
like fixnums.

reduce its hash down to a fixnum.
* doc/emacs/misc.texi (Shell Ring): Mention history file for

of mini windows more accurately.

* src/fns.c (Fsxhash_eq, Fsxhash_eql, Fsxhash_equal):
Say that hashes are fixnums.
(Fmake_hash_table): Say that that an integer rehash-size
should be a fixnum.
* doc/lispref/hash.texi (Defining Hash): Say that hash and
comparison functions should be consistent and pure, and should
return quickly.

specifying the rotation in degrees (bug#35421).

(bug#36501).
printmax_t etc. were needed only for platforms that lacked
support for printing intmax_t. These platforms are now so
obsolete that they are no longer practical porting targets.

discovered while making these changes. It was introduced in
2011-07-17T00:34:43!eggert@cs.ucla.edu.
