wrapWords(splitLongWords = true) dropped the separator before a word it had to split, fusing it with the word before it. Flush lastSep first, the same as the branch that handles a word which fits. Updates twordwrap's longlongwordRes fixture, which was pinned against the old behavior at three points where a source line break normalizes to a synthetic space.
