Fix tr(1) squeezing

Okay, it took me a while and another look at the Posix spec to see that
I have been dealing with squeezing in a way too complicated way.
What just needed to be done is before doing the final write to deploy
the squeeze-check. We actually do not need this atomically complicated
squeeze check in every single edge-case. Now it should work properly.
