> What system and version are you running? 
Linux (debian amd64), Python is compiled from hg (1ea8b7233fd7).

That's really surprising, because it is all pure Python code and don't
really see how it _could_ be right: take $COLUMNS, subtract, subtract,
and sooner or later _width will go below 0.

Prints -1.

Oh, I just tried it in IDLE and it prints:
  64
  64
  64
  64
  usage: ...
in a very small window (30 cells wide). So IDLE is just doesn't allow you to
go below a certain size.
