Subject: bug#31869: 27.0.50; Character widget unable to read newline character
Date: Sun, 17 Jun 2018 08:39:15 +0200 [thread overview]
Message-ID: <87a7rtsyr0.fsf@web.de> (raw)
Hello,
a recipe for emacs -Q:
(require 'whitespace)
(customize-option 'whitespace-display-mappings)
Make a change and undo it immediately so that the contents are unchanged
but customize lets you "Set for current session". Do that and you get
the
"error custom-variable-set: This field should contain a single
character"
If I remove the entry for the newline character, it succeeds.
For debugging purposes I changed the :valid-regexp of the character
widget definition in wid-edit.el to ".*" and it seems that the newline
character is read in as empty string.
TIA,
Michael.
