I see no need to tell users to type at least 4 hex digits: "C-x 8 RET"
accepts even one digit.  So I think we should use %x here.

Not every Unicode codepoint has a name, so get-char-code-property
could return nil.  E.g., try with any codepoint between zero and #x1f,
inclusive.  When that happens, we should try 'old-name' instead, and
if that returns nil as well (try #x99, for example), I think the "by
name" part should be omitted from the output of describe-char.

Thanks.
