Oh no, not this again. :-(

The ability to run perl on a platform that uses \r as its default line
separator is orthogonal to the ability to process files that might have
originated on such a platform.

Furthermore, there are still Mac OS X programs that use \r as the line
separator.

So, no, I do not think Pod::Html should drop support for it. Why does it
need to? Is it because Pod::Simple does not support it? If not, why not?
If that was removed at some point, I think it should be reinstated.
