[Dillo-dev] can't bind action to backslash

Alexander discovered that binding an action to backslash does not work. I was thinking that the line-continuation code in dGetline came from Tim's work on the parser, but it appears to have been there since the dawn of dillo2. I personally would be tempted to remove the special code for '\' because I'd be surprised if we keep this possibility in mind every time that we use dGetline() somewhere -- and I don't believe it's documented anywhere. But if there's resistance to that, then there are also the options of 1) Making it a line continuation character only if everything following it is whitespace. 2) A special key name for backslash.
