do not display any lone Carriage Returns

In combination with SWITCHES=/N in fdconfig.sys this commit makes
it so only proper CR LF linebreaks are displayed, for instance when
piping dosemu2 output to a file.

SWITCHES=/F will set SkipConfigSeconds so that config.c SkipLine will
display a string reading "\r%79s\r" to delete the prompt that it has
displayed. This overwriting should not be needed for SkipConfigSeconds=0
however. Refer to subsequent commit.
