(emacs)Help Echo

[Luc Teirlinck]

`(emacs)Help Echo' says:

    On most window systems, the help text is displayed as a "tooltip"
    (sometimes known as "balloon help").  *Note Tooltips::.  Otherwise, it
    is shown in the echo area when you move point into the active text.

Unless I am confused, the last sentence is only true if
`help-at-pt-display-when-idle' is t.  If it is nil, the default,
help-echos are only displayed on mouse-over, not on point-over.

What about the following patch to help.texi?  I can install if desired.
