fmt_ulong0 writes an ASCII representation ('0' to '9', base 10) of
\fIsource\fR to \fIdest\fR and returns the number of bytes written.
The output is padded with '0'-bytes until it encompasses at least
\fIn\fR bytes, but it will not be truncated if it does not fit.
fmt_ulong0 does not append \\0.
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ulong0 returns the number
of bytes it would have written.
For convenience, fmt.h defines the integer FMT_ULONG to be big enough to
contain every possible fmt_ulong output plus \\0.
