The DMP library is character-based, whereas the UNIX patch format is 
line-based.  That's why we use a slightly different format.  See this page:
http://code.google.com/p/google-diff-match-patch/wiki/Unidiff

What you have created is a Unidiff parser, which is fine.  But it isn't 
compatible with the patch_toText function.
