tree: fix handling of multi-row stdin input (#54)

This was broken by the GtkColumnView port (7a80b67). As part of
the changes that just stopped any attempt to actually start a
new row here, so we just kept stuffing more and more items into
the only row item we ever create. So you just couldn't do multi-
row input via stdin.
