bug#14238: [PATCH] Help page for character description forgets the character

That's the wrong comparison.  As mentioned `describe-char' is the wrong
name, since what the function does is `describe-pos'.  In contrast
`describe-function' really describes a function and not just "the
function at point" (although the function at point is the one that's
provided as default in the minibuffer).

I've used it to monitor changes to the position's overlays and
text-properties.
