      Ah, so you want to modify what is displayed in place of the folded
      text. This is certainly possible, using the 'foldtext' option.

      If you can specify exactly what you want folded text to look like,
      someone can help you make one. Or you can try your hand yourself.
      There are a couple of examples at :help fold-foldtext and also
      http://vim.wikia.com/wiki/Folding_for_plain_text_files_based_on_indentation
      and http://vim.wikia.com/wiki/Customize_text_for_closed_folds. The
      first link above may be very close to what you are looking for by
      itself.

      The caveat to remember in terms of indenting folded lines is that a
      tab character in the fold text is replaced with a single space, so
      you'll need to do something like this to replace it:

      linetext = substitute(getline(v:foldstart),'^\s\+','\=repeat("
      ",strdisplaywidth(submatch(0)))', '')

      This replaces a sequence of whitespace at the beginning of the line ('^
      \s\+') with a sequence of space characters ( repeat(" " ) of length
      equal to the width of the whitespace sequence as displayed in Vim
      ( strdisplaywidth(submatch(0)) ).
