// stick values like " ok " (with the spaces) in the buttons in an attempt
// to make them look decent. Unfortunately, if they do this the button
// looks way too big in Mozilla. Worse yet, if they do this _and_ set a
// fixed width for the button we run into trouble because our focus-rect
// border/padding and outer border take up 10px of the horizontal button
// space or so; the result is that the text is misaligned, even with the
// recentering we do in nsHTMLButtonFrame::Reflow. So to solve this, even
// if the whitespace is significant, single leading and trailing _spaces_
// (and not other whitespace) are removed. The proper solution, of
// course, is to not have the focus rect painting taking up 6px of
// horizontal space. We should do that instead (via XBL form controls or
// changing the renderer) and remove this.
