^M is usually generated by the <CR> or Enter key on terminals.
On a unix system this is taken to be end-of-line (depending on
stty options selected), which is ordinally represented in a file
by ^J.  Ie. Control-M becomes control-J before it gets to vi.
The way to prevent this is to prefix it with control-V on BSD
systems or "\" on ATT systems.  Note that these prefixes may have
meaning to vi as well, in which case you would have to double up
on them.  Am I wrong about this?  Does vi disable this mode of
the terminal handler?
