The cost to insert N lines at line L is
- [tt.t_ILov + (frame_height + 1 - L) * tt.t_ILpf] +
- N * [tt.t_ILnov + (frame_height + 1 - L) * tt.t_ILnpf]
+ [tt.t_ILov + (frame_lines + 1 - L) * tt.t_ILpf] +
+ N * [tt.t_ILnov + (frame_lines + 1 - L) * tt.t_ILnpf]
ILov represents the basic insert line overhead. ILpf is the padding
required to allow the terminal time to move a line: insertion at line
- L changes (frame_height + 1 - L) lines.
+ L changes (frame_lines + 1 - L) lines.
The first bracketed expression above is the overhead; the second is
the multiply factor. Both are dependent only on the position at
