Inspired by all received answers, I finally came up with a foldtext
function that positions the fold text exactly right, namely
indent(v:foldstart) - foldlevel(v:foldstart) spaces:
function! VhoFoldText() " show the text before the fold marker {{{2
let n = v:foldend - v:foldstart + 1
let l = getline(v:foldstart)
let i = indent(l)
let j = foldlevel(l)
let t = substitute(l, '\*\|\*/\|{\+\d\=', '('.n.' lines)', 'g')
return repeat(' ', i-j) . t
endfunction
Thank you all, and kind regards,
Guido
