[Message part 1 (text/plain, inline)]

This bug report will be sent to the Bug-GNU-Emacs mailing list

and the GNU bug tracker at debbugs.gnu.org.  Please check that

the From: line contains a valid email address.  After a delay of up

to one day, you should receive an acknowledgement at that address.


Please write in English if possible, as the Emacs maintainers

usually do not have translators for other languages.


Please describe exactly what actions triggered the bug, and

the precise symptoms of the bug.  If you can, give a recipe

starting from `emacs -Q':


putting (global-whitespace-newline-mode) in my init.el file makes all

whitespace appear, not just newlines. the work-around that jlp gave me

is to use '(whitespace-style (quote (newline newline-mark))) but he said

it's definitely a bug that i should report.


If Emacs crashed, and you have the Emacs process in the gdb debugger,

please include the output from the following gdb commands:

    `bt full' and `xbacktrace'.

For information about debugging Emacs, please read the file

Thanks for the report.
global-whitespace-newline-mode basically does this:

(let ((whitespace-style '(newline-mark newline)))
  (global-whitespace-mode 1))

So it does the right thing in existing buffers, but not in future
buffers that are created later (because whitespace-style is back to its
default value).

I don't know why global-whitespace-newline-mode even needs to exist.
It would be simpler to remove it and just say "customize
whitespace-style to whatever you want, and call global-whitespace-mode".

Makes sense to me, so I've now obsoleted it in Emacs 28.
