There's also a pre-existing bug that a view without a trailing newline loses its last line on exit. close moves to the last buffer row and erases below it, so the shell prompt overwrites that line. Maybe worth fixing here too

parking at the frame's last row is correct, but for frames taller than the screen this now aligns the frame with the top of the terminal, and the existing per-frame full redraw then floods scrollback in tmux

this checks the parked position but not that a second unchanged flush is a no-op. that's why the regression above was missed

This revision maintains trailing newlines, because trailing blank lines can be a design choice. Prior to this change it was nearly impossible to keep them.
Worth testing this one thoroughly, per the removed comment in the code.
