Hiding ^M in emacs

Sometimes I need to read log files that have ^M (control-M) in the line endings. I can do a global replace to get rid of them, but then something more is logged to the log file and, of course, they all come back.

Setting unix-style or dos-style end-of-line encoding doesn't seem to make much difference (but unix-style is my default). I'm using the undecided-(unix|dos) coding system.

I'm on windows, reading log files created by log4net (although log4net obviously isn't the only source of this annoyance).

Any hints?

(defun remove-dos-eol ()
  "Do not show ^M in files containing mixed UNIX and DOS line endings."
  (interactive)
  (setq buffer-display-table (make-display-table))
  (aset buffer-display-table ?\^M []))

Solution by Johan Bockgård. I found it here.

Modern versions of emacs know how to handle both UNIX and DOS line endings, so when ^M shows up in the file, it means that there's a mixture of both in the file. When there is such a mixture, emacs defaults to UNIX mode, so the ^Ms are visible. The real fix is to fix the program creating the file so that it uses consistent line-endings.
