A terminal's body reads as logical lines, the last one ending in a newline

A terminal's body came back as the screen's rows, a long line cut where the
terminal wrapped it and the last line with no newline. The body (and a
terminal's Save, and the length its ctl reports) now joins wrapped rows by
ghostty's wrap flags, as pty/run's output does, and ends the last line with
a newline.
