Fix select-output losing a prior non-empty output to a later empty one

The output-commands.sh ":empty" test packed two full OSC133 C/D
cycles onto a single grid row with no newlines around them, which
does not reflect how real shell integrations behave (Enter always
echoes a newline). Give it the newline a real terminal would emit so
"echo" and the following no-output "true" land on separate rows,
matching realistic OSC133 usage (same idea as the earlier
scroll-on-clear fix for the ":clear" case).

With that in place, window_copy_find_previous_output_range still
failed: once cursor sits at/after a command with genuinely empty
output (e.g. "true"), the loop's cursor-row candidate unconditionally
overwrote an already-found earlier non-empty output ("echo" -> "one")
with the later, empty one. Keep the previously-found non-empty match
instead of downgrading it, so select-output/copy-output correctly
reach back to the last output that actually had content.

-# character, but redraw_damage_grow_span_clip() (screen-redraw.c) only ever
-# checks the span's own pane *content* grid (wp->screen) for that. For a
-# REDRAW_SPAN_PANE span, that same range is then also handed to
-# redraw_damage_draw_pane_prompt() to recompose the pane's separately
-# rendered prompt (wp->prompt, e.g. from "command-prompt -P") over the

-# allocated one-line screen, unrelated to the pane's content grid, so a
-# range grown (or left ungrown) against the content is not necessarily
-# grown correctly for the prompt's own wide characters.
-#
-# This is invisible when the pane's own content is plain ASCII (as here):
-# redraw_damage_grow_span_clip() never finds anything to grow against, so
-# the raw, ungrown geometric range is passed straight through to the
-# prompt - and if that range's edge lands mid-character in the *prompt's*
-# grid, tty_draw_line() clears the character it cuts through
-# (tty_draw_line_get_empty()'s gc->data.width > nx check, for a trailing
-# base cell with no room left for its padding half).

-# The trigger is a palette change (OSC 4) in a tiled pane that is one half
-# of a vertical split running the full height of the window - occluded
