unified diff parser in unified-diff-parser branch parsing issues #46

hi

a unified diff such as the one below is not parsed properly. i do see that the parse complete however the fromFile gets updated with the content of the line '---' out of the line fragments. essentially the fromFile is "some comment" after the parse.

read the above unified patch into using

  val diff = UnifiedDiffReader.parseUnifiedDiff(diff_file)
