bug#52392: 29.0.50; org-priority 'SPC to remove' doesn't work

[Bruce E. Robertson]

1. in init.el:
(custom-set-variables
 '(org-priority-default 32)
 '(org-priority-highest 0)
 '(org-priority-lowest 31)
)
2. position to line in .org file:
** TODO [#0] test line

3. from M-x view-lossage:
 C-c ,         ;; org-priority

4. mini-buffer displays:
"Priority 0-31, SPC to remove: "

5. further in view-lossage:
SPC           ;; self-insert-command
 <return>      ;; exit-minibuffer

4. from *Messages* (and mini-buffer):
Priority of current item set to 0

5. PROBLEM:
I wanted to remove priority.

6. WORK-AROUND:
set priority to 32. Then priority disappears. Perhaps this is because 32
is space code or because I've set org-priority-default to 32.
( I spent a medium amount of time to find this behavior. )

7. SUGGESTION:
rewrite org-priority to have a clear distinction between numbers and
characters and whatever will be used to remove the priority.
( I gave a look at this but my emacs-fu is too weak. Or my time-fu is
too small. )

Thank you, thank you, thank you for emacs and org-mode and ...

This looks like a duplicate of https://debbugs.gnu.org/52341 (which has
already received comments), so I'm merging the reports.
