The program appended below does what you want on an entire directory
hierarchy. I wrote it back in the days when I frequently needed to
handle Mac text files. It'll work on those files too. It even creates
timestamped backup files.

For those of you who're wondering why I wrote:

    s/\015\012?/\012/g;

instead of the (nicer looking):

    s/\r\n?/\n/g;

It's because the former is more portable. The meaning of \r and \n
changes depending upon the platform.
