bug#2938: 23.0.91; elisp.info: auto-resize-tool-bars

In the elisp.info, there is reference to the variable:

 -- Variable: auto-resize-tool-bar
     If this variable is non-`nil', the tool bar automatically resizes
     to show all defined tool bar items--but not larger than a quarter
     of the frame's height.

     If the value is `grow-only', the tool bar expands automatically,
     but does not contract automatically.  To contract the tool bar, the
     user has to redraw the frame by entering `C-l'.

I think that should be 'auto-resize-tool-bars'.  Also, from my limited
experimentation, it seems that variable does not apply on unix with gtk
or mac (under nextstep); if a frame is narrowed, the toolbar gains a
right-arrow icon which shows the remaining icons, rather than moving the
icons onto a second line.  Should the doc string mention this
restriction?  In the elisp.info file, when describing Layout Parameters,
it does say:

`tool-bar-lines'
     The number of lines to use for the tool bar.  A value of `nil'
     means don't display a tool bar.  (GTK allows at most one tool bar
     line; it treats larger values as 1.)

which confirms to me that GTK will not show multi-line tool bars.  But I
also saw the same behaviour on the mac under nextstep.
