       #include <fmt.h>

       size_t fmt_plusminus(char *dest,signed int source);

DESCRIPTION
       fmt_plusminus writes '-' to dest if source is negative, '+' if source
       is positive, nothing otherwise.  It returns the number of bytes
       written.

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