Those lines aren't added by the script; they are added by Vim itself
and the foldtext() function, which is the default value of the
'foldtext' option. See

:help foldtext()
:help 'foldtext'
:help fold-foldtext

As described in those help topics, you can create your own
'foldtext' expression or function to format the fold lines as you
like.

As an example, here is the 'foldtext' function from my ~/.vimrc that
I use for almost all my folding.

set foldtext=MyFoldText()
function! MyFoldText()
let n = v:foldend - v:foldstart + 1
let i = indent(v:foldstart)
let istr = repeat(' ', i)
return istr . "+-" . v:folddashes . " " . n . " lines "
endfunction

Gary
