Subject: 30.1; global-whitespace-mode doesn’t enable
 whitespace-mode in remember-notes buffer
Date: Wed, 13 Aug 2025 02:36:48 -0400

Hello Emacs Maintainers,  global-whitespace-mode does not enable 
whitespace-mode in remember-notes-buffer-name buffer.  This 
happens because whitespace-enable-predicate prevents 
whitespace-mode from activating in buffers whose names start with 
‘*’, with only *scratch* being an
exception. While it makes sense for buffers like *Messages* or
*Ibuffer*, it unintentionally affects remember-notes-buffer-name
buffers, which should likely be treated similarly to *scratch*.

Steps to reproduce:

emacs -Q

M-x global-whitespace-mode
M-x remember-notes
C-h v whitespace-mode

Value of whitespace-mode is nil, indicating whitespace-mode is not
enabled in the remember-notes-buffer-name buffer

Thank you for your time!

Patches to add a user option that allows to make exceptions for more
than just *scratch* will be welcome.

Thanks.
