Would love to have this!

Here is one of my recent use case: "quote bashslash in a shell command".

    The shell command is:
      echo foo.bar | sed -e 's/\..*//'
    which will produce "foo" on bash.
    If i try to pass it to shell-command-to-string:
      (shell-command-to-string "echo foo.bar | sed -e 's/\..*//'")
        => "\n"
    Then i find i need to quote the backslash in emacs once more:
      (shell-command-to-string "echo foo.bar | sed -e 's/\\..*//'")
        => "foo\n"
    Is there a function or other way that can handle this kind of backslash
    quoting automatically?
