I think the idea is to be able to *interactively* enter rx syntax
and have it highlighted (as opposed to `highlight-regexp' which will
obviously treat what you enter interactively as an actual regexp,
rather than something to be transformed into one).

i.e. These would be equivalent:

M-x highlight-rx RET (or "foo" "bar") RET
M-x highlight-regexp RET \(foo\|bar\) RET
