^M is Control-M which is Carriage Return.

You're editing a DOS file, basically. Doing:

perl -e 'while(<>) { s/\r//g; print; }' <some-dos-file >some-unix-file

will translate the DOS line terminated "some-dos-file" into the UNIX
line terminated "some-unix-file".

Or just download them in ASCII mode via FTP, since that's what ASCII
mode is for - changing line termination. (Okay, it'll also convert EBDIC
to ASCII for transmission over the wire, too.)
