Agreed. It was better to start with something cleaner. So, I created a
whole new prettify-text API and reimplemented auth-source-reveal-mode on
top of it. It worked well in my testing.

The new branch is scratch/tzz/prettify-text-mode (I left
scratch/tzz/auth-source-reveal-mode in place as a reference).

The new code won't interfere with existing `prettify-symbols-mode'
users. Eventually `prettify-symbols-mode' could be migrated to this new
API to avoid the code duplication in the post-command-hook and
elsewhere.

If you have suggestions or comments, please let me know. I'll document
the API before I push the branch out.
