the inaccuracy in log is independent of the other problems.
I do not know how accurate the calculation of the width
of objects must be calculated to get reasonably placed
output. Is it better to overestimate the space needed?
If the output routines require exact width calculations,
one should consider to calculate the exact print width.
Besides, is the calculation of a logarithm really less
expensive than the exact integer calculation for a 
fixnum (bignums are handled differently)? Even if it is,
does it matter?
