A pane's last row of text is no resize handle; the grip is, and the GUI's rule

A press on a pane's last row began a seam drag, so the row could not be
clicked or swept like the rest of the text (rsearch dragged the handle out
of the way first). Now no row of text is a handle: in the GUI a press on
the 2 px rule between two panes drags their seam, and anywhere the grip
does, as acme's button moves a window -- dragged up or down its own column
it moves the pane's top, either pane down to its tag alone (acme's
coldragwin), dragged down inside itself too. The hover hint over a last row
is gone; column edges resize as they did. Scripts that dragged a seam drag
a grip instead and match their goldens; six goldens lost the hint or moved a
cursor to the clicked text, re-recorded by name.

  A new file opens in a new COLUMN only if both panes would still get
  100 columns of width. Otherwise it stacks in the one you are in.
