# WHAT ONE PRESS OF `n` TAKES, and why that is not one answer. A pane's rows
# decide it (output_pane.Grain, read in Pardes.lookSpanIn):
#
#   free text — a terminal, a file, a PDF — is stepped WORD by word, several
#   stops to a line, because a line of it may name several places at once (the
#   `ls` row in ttylook.snap hops big.txt -> plain.txt -> sub);
#
#   a RESULTS BUFFER is stepped ROW by row, on the location at the head of the
#   row, because a row there IS one location and the words after it are the
#   MATCHED TEXT — the same hit, spelled out. That text is full of look-able
#   words, and stopping on them was stopping on the same result twice.
#
# This script is the second rule. Row 2 below matched on a line that mentions
# `sub/b.txt`, so the old word-grained walk stopped there before it ever
# reached row 3; now `n` presses and rows correspond one to one, and the fourth
# press wraps the ring back to row 1.
#
# LARGEST from the head, so a path with a BLANK in it is one span rather than
# the word in front of it: `two words.txt` selects whole and opens.
