# corner grabs on the RIGHT column's side of the v border. The v handle is the
# LEFT column's last cell, so that column's own h hint runs THROUGH it while the
# right column's hints start one cell further right — the crossing there reads as
# a T butting into the junction rather than a full cross, and it is grabbable all
# the same: one drag moves the column edge and the RIGHT column's pane edge.
# Layout: windowops' -n 3 (col 0 x 0 w 50, panes on rows 1-15 and 16-29; col 1
# x 50 w 50), then focus right and Alt-n so col 1 holds two panes as well, split
# at ITS own row. The two corners on col 49 are then row 16 (col 0's seam, the
# one that already worked) and row 5 (col 1's, the one this script is about).
