print -c fixes

[Zefram <A.Main@xxxxxxxxxxxxxxxxx>]

-----BEGIN PGP SIGNED MESSAGE-----

This patch fixes a few ugly problems with print -c: spaces were added
to the right of the output to fill the last column; there were
sometimes fewer columns than there could be; and sometimes columns were
separated by more than they should be.  There problems were also
observable with completion lists, except for the extra spaces, and this
patch also fixes these problems there.
