+# The command words of every pane in a LAYOUT COLUMN end at the same screen
+# column. tag_right_pad sets that end, but a path too long to fit inside the
+# pad used to collapse its own gap alone, so one row's New/Del sat hard against
+# its path while the row below it kept its own out at the pad — two ragged
+# columns of words you read (and click) down.
+#
+# Here the file's path is 43 columns longer than the shell's cwd, and long
+# enough (85 of the pane's 98 columns) that its own gap is zero. The shell
+# below it moves out to the file's end instead of the pad's, so both rows spell
+# New and Del in the same two places.

+# A pane whose tag does not FIT is counted AT its right edge rather than
+# dropped from the vote. Dropping it would be a threshold: here the file's tag
+# is 85 columns, so one column of resize either side of that would move BOTH
+# rows of words by the whole pad, and dragging a window edge across the width
+# would snap them back and forth under the pointer. 87 -> 86 moves them one
+# column, and the file's own tag is the only thing that loses a character.

+# A left click on a tagline SEEDS its tail: the gap stops being computed and
+# becomes ordinary characters you own. It must not stop the pane VOTING —
+# this clicks the FILE's path, and the file is the widest tag in the column,
+# the one holding the end out. The shell's row below must not move a column
+# (it did once: every other tagline in the column snapped left on the click,
+# and a middle-click that used to hit Del landed on whitespace).
