* lisp/format-spec.el: Use lexical-binding. Remove dependence on
subr-x.el.
(format-spec-make): Clarify docstring.
(format-spec--parse-modifiers): Rename to...
(format-spec--parse-flags): ...this and simplify. In particular,
don't bother parsing :space-pad which is redundant and unused.
(format-spec--pad): Remove, replacing with...
(format-spec--do-flags): ...this new helper function which performs
more of format-spec's supported text manipulation.
(format-spec): Autoload. Allow optional argument to take on special
values 'ignore' and 'delete' for more control over what happens when
a replacement for a format specification isn't provided. Bring back
proper support for a precision modifier similar to that of 'format'.
* lisp/battery.el (battery-format): Rewrite in terms of format-spec.
(battery-echo-area-format, battery-mode-line-format): Mention
support of format-spec syntax in docstrings.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
gnus.texi (Listing Groups): Document gnus-group-list-ticked.
gssapi.el (open-gssapi-stream): Remove the last mentions of the IMAP stuff.
gnus-score.el (gnus-score-string): Fix calling convention of `gnus-simplify-buffer-fuzzy' after last patches.
gnus-sum.el (gnus-update-marks): Don't send any marks updates to the server for articles we didn't get any headers for. This is a sanity check.
nnimap.el (nnimap-open-connection-1): Is the login responds with a new CAPABILITY, use it.
gnus-agent.el (gnus-agent-fetch-headers): Don't message if we're not downloading anything.
gnus.el (gnus-splash-svg-color-symbols): Removed superfluous `and'.
gnus.el (gnus-group-startup-message): Prefer svg file and replace colors.
(gnus-splash-svg-color-symbols): New function.
gnus-sum.el (gnus-simplify-buffer-fuzzy): Take the regexp explicitly instead of using the global gnus-simplify-subject-fuzzy-regexp.
(gnus-simplify-subject-fuzzy): Use the local gnus-simplify-subject-fuzzy-regex instead of the global one. This makes using this variable in group parameters work.
gnus-registry.el (gnus-registry-unfollowed-groups): Add "archive:sent" to the unfollowed group regex (for the recent Gnus archive:sent-YYYY-MM-DD groups).
(gnus-registry-split-fancy-with-parent): Bail out early in sender tracking if there are more than `gnus-registry-max-track-groups' matches.
message.el (message--yank-original-internal): New function to do the insertion cleanly inside eval in `message-yank-original'.
(message-yank-original): Use it.
message.texi (Insertion Variables): Document message-cite-style.
nnimap.el (nnimap-open-connection-1): Allow `network-only', too.
gssapi.el: New file separated out from imap.el to provide a general Kerberos 5 connection facility for Emacs.
message.el (message-elide-ellipsis): Document the format spec ellipsis.
message.el (message-elide-region): Allow the ellipsis to say how many lines were removed.
gnus-win.el (gnus-configure-frame): Protect against trying to restore window configurations containing buffers that are now dead.
nnimap.el (nnimap-parse-flags): Remove all MODSEQ entries before parsing to avoid integer overflows.
(nnimap-parse-flags): Simplify the last change.
(nnimap-parse-flags): Store HIGHESTMODSEQ as a string, since it may be too large for 32-bit Emacsen.
gnus-art.el (gnus-article-treat-body-boundary): Fix boundary width on XEmacs, which was one character too wide.
gnus-sum.el (gnus-articles-to-read): Use gnus-large-newsgroup as default number of articles to display.
(gnus-articles-to-read): Use pretty names for prompt.
gnus-int.el (gnus-open-server): Ditto.
gnus-start.el (gnus-activate-group): Give a backtrace if debug-on-quit is set and the user hits `C-g'.
(gnus-read-active-file): Ditto.
gnus-group.el (gnus-group-read-ephemeral-group): Ditto.
