Improve lossless compression.
This is essentially a revert of a3611513d2bf465fd282d9dc45b3f72c79c232ad
and cfbcc5ece022fc74ae9b987e05c2807df0d82ec5.
Here is what happened: there was a corruption bug that eventually
got fixed by 0174d18d8b51f6c9228c70066a987c30a8132995.
But before finding the root, a3611513d2bf465fd282d9dc45b3f72c79c232ad
and cfbcc5ece022fc74ae9b987e05c2807df0d82ec5 hid the bug
by not imposing length of 1 when it was actually 2 or 3 (which does help
compression as a litteral is more efficient than an offset and a length
of size 2 or 3).
