Bruno Haible reported that grantpt and unlockpt report success even on
invalid fds. This program fails the assertion at line 7:
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>
int main (void)
{
assert (grantpt (-1) == -1);
assert (errno == EBADF);
errno = 0;
assert (grantpt (99) == -1);
assert (errno == EBADF);
return 0;
}

I checked in a simple fix for this.
