I found a whole bunch more problems than this :-(.  I've committed a
cleaned-up version that seems to work correctly in a simple standalone
testbed, but it'd be a good idea to exercise it inside PG as well.
Can you try regression tests and the factorial() problem on CVS tip?

The problems are sufficiently bad that it might be a good idea to
backport the fixes into 8.0 and before as well --- but I note that
the ABI is different (pg_snprintf vs snprintf, etc) so this requires
a bit of investigation rather than just committing the file as-is.
