Hello,

I would like to submit a patch to allow users to change the priority
tag's form entirely. While it has been working for my use-case i.e
basic operations inside org buffers and org-agenda, it is not perfect
and there are some bugs that remain when using more advanced features
with different tag forms (mine is `_p' where `p' is `[1-9]'), that I am
not competent enough to solve. However I believe there are no breaking
changes if the user does not modify said tag form. If there's any
precision I can add, please let me know.

Subject: [PATCH] org-priority: allow customization of priority indicator

* org.el (org-priority): Allow the user to set the prefix and suffix
of the priority indicator so that it have a completely different form
for them (e.g _A instead of [#A]).
