oops, this should be:
function! VhoFoldText() " show the text before the fold marker {{{2
let n = v:foldend - v:foldstart + 1
let i = indent(v:foldstart)
let j = foldlevel(v:foldstart)
let l = getline(v:foldstart)
let t = substitute(l, '\*\|\*/\|{\+\d\=', '('.n.' lines)', 'g')
return repeat(' ', i-j) . t
endfunction
Sorry for the erroneous version,
Kind regards,
Guido
