I don't think it's possible. It's a good use case for raw strings
(which I've tried to get in vanilla emacs [1]) or more generally
reader macros (see Pascal's post).

But what you can do is copy and paste your shell code, select it, and
call this function:

(defun my-raw-string (start end)
  (interactive "r")
  (let ((r (prin1-to-string (buffer-substring-no-properties start end))))
    (delete-region start end)
    (insert r)))

which will turn this:

a b \ c

to this:

"a b \\ c"
