Hi,

I do

(setq standard-display-table (make-display-table))
(set-char-table-extra-slot standard-display-table 3
                           (+ (lsh (face-id 'secondary-selection) 19) ?^))

to make ^ in control characters stand out.  (I've also got \, ..., sticky
space and soft hyphen that way, with the same effect.)

If a line gets wrapped, such that the special character is the first on the
continuation line, the rest of the visible buffer part will be in
secondary-selection.

If there are more special characters further down, this face will go on and
off for "random" (i.e. not understood) stretches.  They vary when I edit in
between.

Apart from this diplay bug, I find this feature so useful, it should be on by
default with a dedicated face.  Otherwise it's so obscure, few people will
find out about it.

coralament / best Grötens / liebe Grüße / best regards / elkorajn salutojn
