It's a heuristic about where rl_point should go. If the line is expanded,
you lose where point was in relation to the expanded alias, so the
function assumes you expanded a word to a word and skips to the end of it.
It doesn't check to see whether or not any aliases were expanded, or
whether the expanded line differs from the original one.
