linenoise: fix multi-line issues with long lines

* linenoise/linenoise.c (screen_rows): Restructured.
Calculates correct cursor rows (out.rows[1]).  It's now
possible that the reported cursor row exceeds the number of
rows (out.rows[0]), because the cursor is on the last line,
which itself doesn't wrap, but the cursor does.
(refresh_multiline): Cursor wrapping calculation is
simple now: just check that nrow > rows.
Coalesced code for dealing with cursor position.
