fmt_minus - write '-' for negative integers

       fmt_minus writes '-' if source is negative, nothing otherwise.  It returns the number of bytes written.

       fmt_minus does not append \0.

       If dest equals FMT_LEN (i.e. is zero), fmt_minus returns the number of bytes it would have written.
