^M (M may be any of @, A-Z, [, \\, ], ^, _) is some software's way of
showing a control character, a non-printable or whitespace character.
The general way to do the same thing in perl is to use \cM (in a
double-quotish context such as a substitution or "string").  But as
mike points out, \cM is one that's given an escape sequence all of
it's own, \r.
