        [should be echo -n "$line$n" or echo -n "$line"; echo ]
      [but that fails on \c machines ]
    [preprocess with sed 's-\\-\\\\-g' or various others ]

Oh, gimme a break. Your suggestion of switching to SVR4 doesn't work on
any machine. :-) It's trivial to select between the two scripts with an
echo test. There: a perfectly portable sh solution to the problem that
started this thread.

Oh dear. Not paying attention to your quoting? sed s/\\\\/\\\\\\\\/ is
translated by the shell into sed s/\\/\\\\/, which is translated by sed
into s/\/\\/, which is what we want. \c becomes \\c, which is parsed
(correctly) as backslash-c. What makes you think this isn't a solution?
