(Fns_get_selection): Remove unused args `time_stamp' and `terminal'.
(package--update-selected-packages): New function.
(package-menu-execute): Use it before starting the transaction,
this way the list of selected packages is updated even when the
transaction fails.
(package-menu--perform-transaction): Don't edit selected-packages.
* lisp/emacs-lisp/cl-generic.el (cl-generic-define): Don't throw away
previously defined methods.

`el-kws-re'.
The change greatly improves readability, while providing almost the
same (even shorter) byte code: instead of pre-evaluating 10 variables,
tossing them into a list, and destructuring that list a full screen
page later, the variables are simply bound as they are evaluated,
wrapped individually in `eval-when-compile'.

with `--' to avoid ambiguity.

* lisp/vc/vc.el: Update the description of the `diff' function.
* lisp/emacs-lisp/checkdoc.el (checkdoc-error): When `noninteractive'
is non-nil, echo the error with `warn'.
How it can be used in -batch:
(with-current-buffer (find-file "checkdoc.el")
(checkdoc-current-buffer t))
* lisp/vc/vc-annotate.el (vc-annotate-mode-map): Remove duplicate
binding for `v'.
(vc-annotate-show-changeset-diff-revision-at-line): Set up an
appropriate value for default-directory.
No-op by default, only kills term buffer if
`eshell-destroy-buffer-when-process-dies' is non-nil. (Bug#18108)
(eshell-destroy-buffer-when-process-dies): New custom to preserve
previous behavior.
The new buffer syntax '#<buffer-name>' is equivalent to '#<buffer
buffer-name>'. Remove `eshell-buffer-shorthand', as it is no longer

(eshell-get-target): Remove shorthand-specific code.
* lisp/eshell/esh-arg.el (eshell-parse-special-reference): Parse
'#<buffer-name>'.

test for curved quotes being displayable, after switching the
terminal encoding. (Bug#20545)
* src/Makefile.in (lisp.mk): New rule to generate from loadup.el.
(shortlisp_filter): New variable.
(emacs$(EXEEXT), $(etc)/DOC): Depend on lisp.mk.

* Makefile.in ($(MAKEFILE_NAME)): No longer depend on src/lisp.mk.
* lisp/loadup.el: Tweak layout to make it easier to parse.
* make-dist: Do not distribute src/lisp.mk.
* lisp/vc/vc-git.el (vc-git-annotate-command): Use the short date
format (when not overridden with vc-git-annotate-switches).
(vc-git-annotate-time): Support the short format, as well as ISO
8601 that has been used until now (bug#5428).
