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.
These are dates that admin/update-copyright did not update, or
updated incorrectly. Also, back out the copyright-date change to
doc/misc/texinfo.tex, as upstream hasn't updated that date yet.
Moved MH-E image files from toolbar and mail directories into
etc/images.
* mail/reply2.*: Moved to etc/images/mail/reply*.
* toolbar/execute.*, toolbar/highlight.*, toolbar/mh-logo.xpm:
* toolbar/page-down.*, toolbar/show.*, toolbar/widen.*: Moved to
etc/images.
* toolbar/alias.*, toolbar/refile.*, toolbar/repack.*:
* toolbar/reply*: Moved to etc/images/mail.
* toolbar/rescan.*: Moved and renamed to etc/images/refresh.*.
* mh-e/mh-customize.el (mh-refile-msg, mh-tool-bar-reply-from)
(mh-tool-bar-reply-to, mh-tool-bar-reply-all)
(mh-alias-grab-from-field, mh-pack-folder): Image files moved to
etc/images/mail so added "mail/" prefix.
(mh-reply): Ditto. Also renamed reply2.* to reply.*.
(mh-rescan-folder): Ditto. Renamed image file to refresh.* since
it can be used in the general sense. Does not have "mail/" prefix.
