Squelch a compiler warning and get rid of an unnecessary variable.

Just use "sizeof line" for the size of that array; don't have a separate
variable with the number of elements of the array (which at least is
equal to the size of the array, as it's an array of char), as that means
that you have to remember to change both of them.

Then cast "sizeof line" to int, as the second argument to fgets() is an
int, not a size_t (fgets(), as I remember, existed before size_t).
