Ok, the behavior of `completing-read-multiple' has been changed since
the release of GNU Emacs 24.3 with this commit:
http://bzr.savannah.gnu.org/lh/emacs/trunk/revision/112063
The return value of `completing-read-multiple' with empty input is
used elsewhere (e.g. in style/biblatex.el), so we have, at least, two
possibilities:
- everywhere check if the return value is `nil' or `("")';
- treat the two different behaviors inside
`TeX-completing-read-multiple' and always use it. It could be defined
this way
--8<---------------cut here---------------start------------->8---
(defun TeX-completing-read-multiple
(prompt table &optional predicate require-match initial-input
hist def inherit-input-method)
(let ((list
(completing-read-multiple
prompt table &optional predicate require-match initial-input
hist def inherit-input-method)))
(if (equal list '(""))
nil
list)))
--8<---------------cut here---------------end--------------->8---
or something better, in order to make `TeX-completing-read-multiple'
return always nil with empty input.
What do you think?
Bye,
Mosè
