Documentation

Maximum height of a window displaying a temporary buffer.

This is effective only when Temp Buffer Resize mode is enabled. The value is the maximum height (in lines) which resize-temp-buffer-window will give to a window displaying a temporary buffer. It can also be a function to be called to choose the height for such a buffer. It gets one argument, the buffer, and should return a positive integer. At the time the function is called, the window to be resized is selected.

This variable was added, or its default value changed, in Emacs 24.3.
