Whitespace after line continuation breaks syntax highlighting

[eortega-pjr]

sorry if this is already known

RUN echo "foo" \<space> 
    echo "feh"
### no syntax hereafter due to space after \ above

Would have never caught that!

Glad I found this.

encountered this too

It's actually pretty surprising to me that docker accepts that. In most other languages I've used, the backslash is escaping only the next character, which is not a newline in this case. In any case, fixed it in #49

I wouldn't be surprised if the Dockerfile parser trims whitespace off the end of each line.
