Just to check my own sanity I downloaded a copy of PHP 3 to see if that
was the old behavior. It wasn't. Only '.' is converted.
The PHP changes dots to underscores because of the way <input
type="image"> elements behave. If the element has a name, then the
mouse pointer position would be submit as name.x and name.y. In the
days when register_globals was the primary way of accepting input, this
was necessary.
