A couple of `org-priority' fixes

I found a couple of problems in org-priority, I think these patches fix
them.
- The first patch is truly minor, it just adds a bit to the docstring
- The problem which prompted the second patch arises when all priorities
are lowercase (you can test this by evaluating (setq org-priority-highest
?a org-priority-lowest ?z org-priority-default ?o) and then trying to set
the priority to some lowercase letter)
- The problem solved by the third patch arises when numerical priorities
are used and 32 is given as the argument, 32 being the character code of
the space character, because that character is used to signal property
removal.

Subject: [PATCH 2/3] lisp/org.el: Remove (upcase new) in `org-priority'

* lisp/org.el (org-priority): After the new priority is computed,
when checking if it is within the bounds defined by
`org-priority-highest' and `org-priority-lowest', the priority is
upcased, but this leads to an error when all priorities are lowercase
letters.

Subject: [PATCH 3/3] lisp/org.el: Fix priority 32 removing the cookie in
 org-priority

* lisp/org.el (org-priority): When numerical priorities are used, and
the caller supplies 32 as the new priority value, the priority cookie
is removed because this is the code point of the space character. This
patch fixes this so that supplying 32 will change the priority to 32.
