"Section folding
" To see the problem with this:
" go to the last line of a section
" press O
" type Section 2
" press enter
" press up
" zc
" The containing section, not the new one will close. This problem is caused by sections
" overlapping (I think). Vim cannot decide if a line is in one section or the
" next - since the end and the start are the same. Reload and the file works fine again.
