Checking the result of display-images-p doesn't make sense if the
display capabilities when loading the file are different from the
display used to actually look at the widget (which is easily possible
now that Emacs supports both tty and graphic frames in the same
instance).
* lisp/tree-widget.el (tree-widget-image-enable): Default to t,
always. This still shows text on displays that can't show images.
The convention is that a file with Author: but not Maintainer:
means the author is a maintainer, which makes it confusing
when a file lists the same person as author and maintainer.
Avoid the confusion by removing the duplicate Maintainer: line.
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.
Mostly these fixes prevent the transliteration of apostrophes
that should stay apostrophes. Also, prefer curved quotes in
Bahá’í proper names, as that’s the preferred Bahá’í style and
these names are chock-full of non-ASCII characters anyway.
