title: gVim - Pattern not found: ^M when trying to remove newline
body: <p>I am working with gVim in Windows, and when I open files edited by others I see ^M instead of newlines. I have tried using <code>%s/^M/\n/g</code> to replace all instances of ^M with a newline, but I keep getting the error: Pattern not found: ^M. I have also tried <code>%s/^M/\r/g</code>, but I receive the same error.</p>
  
  <p>There are still several instances of ^M in the file, why can't Vim identify them?</p>
