A nitpick on your nitpicks, [\n\r] is a character class, so it works correctly.

    To nitpick further, [\n\r] will replace every instance of \n or \r with a <p>. That means that, on Win32, you'll get two <p> and only one on Unix.
      To put an end to the picking of nits, you will not get two <p>'s under Win32 because the file has not been opened binmode. This means the OS will strip the \r line terminators for you. Also, the correct order for matching in binmode is \r\n, not the other way around.
                     s aamecha.s a..a\u$&owag.print
      To nitpick further doing s///'ing \n and \r separatly is faster using a char class.

        That may be true in general, but the idea is to take the CRLF sequence in Unix (\n) and the CRLF sequence in Windows (\n\r) and replace either of them with <p>. To do that, one regex is simpler than two.
