I am not sure, I understand your problem. Anyway, your function has one
problem. You are deleting lines (including the end-of-line), so you
after the exe "normal! dd" command your file has actually one line less
then before. And the next time you run getline(linenum) you get actually
the wrong line. (which would now be equivalent to linenum+1 and each
time you do normal! dd you add another one)

Christian
