If you don't call 'front' while iterating a ByLine range, you get a different
number of elements.

import std.stdio;
import std.range;
import std.algorithm;
void main()
{
    File("stuff", "w").write("line 1\nline 2\n");
    writeln(File("stuff").byLine.walkLength);
    writeln(File("stuff").byLine.filter!"true".walkLength);
}

This prints:

3
2

This should print 2 in both cases.

Fix Issue 11830 - ByLine range length incorrect.

If you don't call `front` on a `ByLine` range then an extra line is reported.
This change ensures the extra line is consumed when only calling `empty`
without `front`.
