diff for sbin/sysctl.8 man page

Hi,

$ man sysctl
shows=20

Name               Type      Changeable
kern.osreldate     string    no=20

i write a program that fails when reading string,
but when trying read the value as int it works,

for example:

#include <sys/types.h>
#include <sys/sysctl.h>
#include <stdio.h>

void osreldate_as_int() {
        int reldate;
        size_t len =3D sizeof(int);

        sysctlbyname("kern.osreldate" , &reldate , &len , NULL , 0);
        printf("%d\n",reldate);
}

int main() {
        osreldate_as_int();
        return 0;
}

you can see libc, it reads as integer
https://github.com/freebsd/freebsd/blob/master/lib/libc/gen/__getosreldate.c

the line=20
https://github.com/sternix/freebsd/blob/master/sbin/sysctl/sysctl.8#L217
might be=20

.It "kern.osreldate     integer no"

i think,

Thanks.
