From: Andreas Röhler <andreas.roehler@easy-emacs.de>
when running ‘M-x byte-compile-file RET’ with the following form in it,
---
(describe-char-display (point) (char-after))
---
compiler complains:
---
In end of data:
foo.el:6831:17: Warning: the function ‘describe-char-display’ is not known
to be defined.
Which is correct: you need to (require 'descr-text).
Whereas ‘M-x describe-function RET’ tells correctly:
---
describe-char-display is a byte-compiled Lisp function in
‘descr-text.el’.
(describe-char-display POS CHAR)
Which is also correct.
So what is it that you are complaining about here?
