dealing with line endings (and esp in macro packages when verbatim shows 
  up) is always kind of special (add to that dealing with " in mp)

as mplib and metapost are the same you need to take similar measures

when you pipe data from tex to mp or some file - i assume that this is 
which is what latexmp does - you can probably deal with it at the macro 
package level
