Fix corner case bug in numeric to_char().

Trailing-zero stripping applied by the FM specifier could strip zeroes
to the left of the decimal point, for a format with no digit positions
after the decimal point (such as "FM999.").

Reported and diagnosed by Marti Raudsepp, though I didn't use his patch.
