Subject: bug#7208: 23.2; global-whitespace-mode does not survive in buffers changing major mode
Date: Wed, 13 Oct 2010 15:15:57 -0400 [thread overview]
Message-ID: <87aamh52fm.fsf@balanced-tree.i-did-not-set--mail-host-address--so-tickle-me> (raw)
When global-whitespace-mode is enabled, all existing and new buffers get
whitespace highlighting, but the highlighting goes away in any buffer
whose major mode is later changed. You can see this, for example, with
SPC SPC <return> M-x global-whitespace-mode M-x c-mode
I think the fix is to define global-whitespace-mode with
define-globalized-minor-mode, instead of trying to simulate it with
find-file-hook.
