Thanks; I wish this was spelled out in our comments.

The next question is: what code readjusts the location of the locator
window when the source or the command window is resized, and where is
that code called?  because the preceding code in
tui_adjust_win_heights modifies only 2 windows: the one whose height
was directly changed by the winheight command, and the other one,
which is displayed above or below it.
