Not one that worked.  Only the replaceText() worked and then for 
smaller lists.

This is what I tried:

// replaceText version
function shortListDar3 pL, pEx
   return replaceText(pL,"(?m)^" & replaceText(pEx,"\n","\n|^") & 
"\n",empty)
end shortListDar3

// filter version
function shortListDar5 pL, pEx
   filter pL without replaceText(pEx,"\n","|")
   return pL
end shortListDar5
