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.
* lisp/emacs-lisp/lisp-mode.el (lisp-comment-indent): Only check for
open paren if we're looking at multiple comment characters.
* test/lisp/emacs-lisp/lisp-mode-tests.el (lisp-comment-indent-1)
(lisp-comment-indent-2): New tests.
The new lisp-indent-region introduced in 2017-04-22 "Add new
`lisp-indent-region' that doesn't reparse the code." is broken because
it doesn't save the calculated indent amounts for already seen sexp
depths. Fix this by unifying the indent-sexp and lisp-indent-region
code. Furthermore, only preserve position 2 of the running parse
when the depth doesn't change.
* lisp/emacs-lisp/lisp-mode.el (lisp-ppss): Use an OLDSTATE that
corresponds with the start point when calling parse-partial-sexp.
(lisp-indent-state): New struct.
(lisp-indent-calc-next): New function, extracted from indent-sexp.
(indent-sexp, lisp-indent-region): Use it.
(lisp-indent-line): Take indentation, instead of parse state.
* test/lisp/emacs-lisp/lisp-mode-tests.el
(lisp-mode-tests--correctly-indented-sexp): New constant.
(lisp-indent-region, lisp-indent-region-defun-with-docstring):
(lisp-indent-region-open-paren, lisp-indent-region-in-sexp): New
tests.
* lisp/emacs-lisp/lisp-mode.el (calculate-lisp-indent): Let
PARSE-START be a parse state that can be reused.
(indent-sexp): Pass the running parse state to calculate-lisp-indent
instead of the sexp beginning position. Saving the
CONTAINING-SEXP-START returned by `calculate-lisp-indent' is no longer
needed. Don't bother stopping if we don't descend below init-depth,
since we now alway scan the whole buffer (via syntax-ppss) anyway.
* test/lisp/emacs-lisp/lisp-mode-tests.el (indent-sexp): Add blank
line to test case.
