join(1) require input files to be lexicographically sorted. Thus if someone
has a numerically sorted files he must resort them in the lexicographic
order. It is inconvenient.
Linux (GNU) join(1) has an -n option to handle numerically sorted files.
FWIW, I can't find a -n option in GNU join.
Maybe they dropped it or it's undocumented.
