Set TUI locator height to 1

The TUI has long had code to resize the locator, using 2 as the
height.  However the code has "1" in a comment, like:

    locator->resize (2 /* 1 */ ,

This patch fixes the resizing code to set the height to 1.  Doing this
revealed what was probably the reason for setting the height to 2 in
the first place: this caused the locator window to scroll.  However,
this is easily handled by calling scrollok on the locator window.
