A tag that exactly fills its row stays one row, as acme's does

Tags wrapped one cell early to keep a cell for the caret past a full row,
so a tag that exactly filled its column broke as De / l. acme's frame wraps
a box only when it is wider than what the row has left, and frptofchar
clamps the tick past a full line's end to the frame's edge. Tags now wrap
at their full width; the caret past a full row sits at the tag layer's
edge, and on the pane's last cell in a terminal grid, which has none past
it. Two tiny-screen tests collapse their tags, as the others do, and the 41
goldens that moved were re-recorded by name after the same check: rows
shift back up under the shorter tags and nothing else changes. chordcut's
file-body clicks moved back with them.
