Blead breaks DBD::SQLite

This partially reverts 0f12654f40.

The particular spot being reverted is in gv.c, and the change did not
take into account all the nuances involved, so simply revert it.  I
believe what is happening is that a negative number is being generated
and treated as a very large number.  Instead the code should retain the
original test that it was ok to do the subtraction, before actually
doing it.
