Doesn't read any line ending (CR, LF, or CR/LF) #3
Description
Because your code uses the std::getline function to get the text, it does not accept line endings except those recognized by the current platform. This Stack Overflow article gives a nifty replacement for getline that recognizes all line endings. I suggest adding this would be a good addition to your excellent parser.
