cmd/digraph: omit unnecessary empty lines in focus

There's currently a bug which will print additional lines, since append adds to
the end of an array instead of starting from the first open position. That cause
strings.Join to print empty lines for each of the pre-allocated array elements.
So, this CL changes the make to set capacity instead of len, and sets len to 0.
