I've applied this patch along with followup changes to pg_dump (it sets
extra_float_digits to 2 to allow accurate dump/reload) and the geometry
regression test (it sets extra_float_digits to -3).

I find that two geometry 'expected' files are now sufficient to cover
all the platforms I have available to test. (We'd only need one, if
everyone displayed minus zero as '-0', but some platforms print '0'.)
I tested on HPUX 10.20 (HPPA), Red Hat Linux 8.0 (Intel), Mac OS X 10.2.1
and LinuxPPC (PPC).

I'd be interested to hear results of testing CVS tip (now 7.4devel)
on other platforms. Does geometry pass cleanly for you?
