Details:
screen -X echo '\' produces an error instead of printing \.
: Missing " quote.
According to amade it's the same with the newest version.
One could argue that a single unescaped backslash is not valid but then I
think at least the error message should be improved.
I suggest to do it similar to printf though which just prints the \ in this
case.
It seems to me that the backslash escape and quote handling could be improved
in general.
screen -X echo '\"\"\r\n\t' does not seem to do much useful. Perhaps it'd be
better to not interprete backslash escapes or quotes at all.
