Do not do backslash excape processing on any unquoted strings in dot-commands

in the CLI - on Windows or on posix-like systems either one.  This brings the
processing into alignment with the documentation, allows backslash-delimited
filenames on Windows (as long as they are unquoted), and causes the CLI to work
the same with regard to backslash escapes on both Windows and posix.
