hGetLine does not document whether newline is returned.

Current documentation on hackage:

hGetLine :: Handle -> IO String

Computation hGetLine hdl reads a line from the file or channel managed by hdl.

This operation may fail with:

isEOFError if the end of file is encountered when reading the first character of the line.

If hGetLine encounters end-of-file at any other point while reading in a line, it is treated as a line terminator and the (partial) line is returned.
