The code is doing exactly what it says.  getTwoChars reads two characters
--- *not* a line.  So the next character waiting to be read is the newline,
which is returned by the next getTwoChars.

This may depend to some extent on the platform, as Unix defaults to a
line-oriented input interface (at the OS level) but Windows to
character-oriented input.
