The command `what-cursor-position' reports that SPC has `nobreak-space'
face, which isn't true.

[How to reporoduce]
1. emacs -Q
2. Type SPC C-b C-u C-x =
3. In *Help* buffer, there is a line saying
       hardcoded face: nobreak-space

I think this is a bug. SPC actually has no particular face;
`nobreak-space' face has underline (at least on my display), but the SPC
is displayed without underline.

Here is the responsible code in descr-text.el:
----------------------------------------------------------------------
(defun describe-char (pos &optional buffer)
[...]
                            ((and nobreak-char-display char
                                  (eq (get-char-code-property char 'general-category) 'Zs))
                             'nobreak-space)
----------------------------------------------------------------------
This conditional should exclude the case that `char' is ASCII space.

Regards,
Ikumi Keita
