Also add some tests for braces and parse-partial-sexp amongst Lisp style
comments.
* test/src/syntax-tests.el (\;-in, \;-out): Add syntax for { and }.
(top-level): Add new tests for Lisp style comments.
(\#|-in, \#|-out): New functions.
(top-level): Add new tests for nested Lisp style comments, and mixtures of
nested comments with "ordinary" comments.
* test/src/syntax-resources/syntax-comments.txt (top-level): Add new test
fragments for #|...|#, etc.
This now tests the interface between parse-partial-sexp and the low level
comment function in syntax.c
* test/src/syntax-tests.el (syntax-comments-midpoint): New function.
(syntax-pps-comments): New macro.
(top level): Two new syntax-br-comments tests and five new syntax-pps-comments
tests.
* test/data/syntax-comments.txt (top level): Amend some test fragments and add
some more.
This now tests the interface between scan_lists and the comment functions.
* test/src/syntax-tests.el (syntax-br-comments): New macro.
({-in, ;-in, /*-in): Set parse-sexp-ignore-comments to t.
(top level): Add 15 tests for comments inside brace lists.
* test/data/syntax-comments.txt (top level): Amend some test fragments.
* test/src/syntax-tests: Add a new section testing some aspects of comment
handling in syntax.c. This needs further enhancement. It uses ....
* test/data/syntax-comments.txt: A new test file.
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.
Characters having both open paren syntax and comment start syntax were
being detected as open parens even when they should have been part a
comment starter (Bug#24870).
* src/syntax.c (in_2char_comment_start): New function, extracted from
`scan_sexps_forward'.
(scan_sexps_forward): Add check for a 2-char comment starter before the
loop. Inside the loop, do that check after incrementing the 'from'
character index. Move the single char comment syntax cases into the
switch instead of special casing them before.
* test/src/syntax-tests.el (parse-partial-sexp-paren-comments):
(parse-partial-sexp-continue-over-comment-marker): New tests.
