Good point --- I had forgot about FM.  In that case there *is* a bug
here, but I'm not sure if it's with to_char or to_number:

regression=# select to_number(to_char(1000, 'FM999,999'),'FM999,999');
(1 row)

regression=# select to_number(to_char(1000, '999,999'),'999,999');
(1 row)

Whatever your opinion is about the behavior of the non-FM format, surely
to_char and to_number should be inverses.
