Re: Suggestions for the temporary windows used from the minibuffer

[Richard M. Stallman]

    This is for use with help in isearch mode. It adds the text 
    X-DESCRIPTION to the text that is normally shown when you type C-h. It 
    also binds the character X-CHAR to the function X-FUNCTION in keymap 
    used in C-h help. This is only done for isearch, otherwise the new 
    optional arguments X-FUNCTION, X-CHAR and X-DESCRIPTION are not used.

That explanation would help, I guess.  But I don't understand the
point of it.  Could you tell us the point?

    Maybe it would help to say "See isearch mode for an example"?

It would help some, but an explicit explanation here of that example
would help more.

    There is a comment right over still-map (though it is short). I can add 
    some more comment here of course, like ";; Copy the keys from the users 
    current key bindings that still should be available (ie keyboard 
    scrolling with Page Up/Down)".

That would more or less suffice for this point.
However, I find the word "still" confusing;
I don't think it fits this.
