Fixes #617 ... for now.
The problem was that some codes are assuming the newline in the input code is always '\n'. Especially, str.starts_with('\n') was breaking danger because it always fail in CRLF environment.
I'm still feeling uncomfortable that so many codes seems to not consider CRLF env, but fortunately str.ends_with('\n') and str.contains('\n') both work properly under CRLF env. At least, no tests are broken in Windows anymore.
Need to push #2028 beforehand to check if the tests are really fixed under Windows.
