A pane tag wraps onto rows and can collapse to one, as acme's does

acme's frame wraps a tag at its right edge and the window grows to show
every row (wind.c wintaglines); Tagup/Tagdown shrink it to one row and back.
Pane tags used to be one row, scrolled sideways to the caret. Now a tag's
lines wrap at its width (one cell kept for the caret past a full row) and it
starts expanded; insert-mode Up on the first row collapses it, Down on the
last row expands it, and Alt-Up/Alt-Down do so in either mode. A word the
wrap breaks across rows is still one word to a click and a selection.
Column and workspace tags keep scrolling sideways.

Tests read body rows relative to the body's first row; the 41 snapshot
goldens that moved were re-recorded by name after a programmatic check that
each differs only by body rows shifting under the taller tags, and twelve
scripts whose clicks targeted fixed rows now click the same text.
