Comment(by cremona):
It's a very good idea to have verbose=True cause output of precision
changes.
Testing hints: it's no good giving input which is already saturated since
eclib will prove saturation without using any floating point arithmetic at
all. You need to give unsaturated input, and there is no need to have
rank>1 to exercise the precision code, so loop through the (extended)
database, pick rank one curves E with generator P and run
E.saturate([k*P]) for small k>1.
OK, so I should do this.
