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.
Same comments as per 2012-05-01T06:59:34Z!rgm@gnu.org, for lisp/term:
Not that compiling these will bring any noticeable speed benefit, but
there's really no reason not to compile them. The extra disk space
and build time is negligible, and it might reveal use of obsolete
functions, bugs, etc.
they used to do some other jobs than what done by
set-language-environment, those jobs are done in
setup-XXX-environment-internal now.
("LANUGAGE-ENVIRONMENT"): Delete property setup-function or change
the value to setup-XXX-environment-internal. Add properties
nonascii-translation, input-method, features, unibyte-syntax, and
unibyte-display.
