NAME
       fmt_minus - write '-' for negative integers

SYNTAX
       #include <fmt.h>

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

DESCRIPTION
       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.
