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.

non-nil, the list is printed by only adding and deleting the
changed entries, instead of erasing the whole buffer. This method
is much faster when few or no entries have changed.

padding is 0; otherwise, field width is not respected unless the title is as
wide as the field.
* lisp/ebuff-menu.el (electric-buffer-list): Put electric buffer menu
command descriptions in this docstring, instead of the docstring
of electric-buffer-menu-mode. Code cleanups.
