Improper handling of slash-escaped control characters

[Kyle J. Davis]

With this module:
> set test "one\\ntwo"
Yields (in real redis-cli monitor):
"set" "test" "one\\\\ntwo"

While real redis-cli with the same command:
"set" "test" "one\\ntwo"

I am not sure. But it seems that node tacitly escapes backslash \
to \\ while reading from stdin, likely util.inspect has been used.
