Fix multiline remove in lineArray

I forgot that when you remove lines[n] then lines[n+1] becomes lines[n]
so to remove the range lines[a:b] you need to remove lines[a] for a-b
times. In this case we should delete lines[start.Y + 1] over and over
instead of removing lines[i] because i is contantly increasing.

Fixes #166
