This causes confusion for new users when they get told to not use those variables because of how they interact with sort and friends. This changes them to `$x` and `$y`, and also changes nearby variables to keep things consistent, such as `$c` -> `$z` and `@a` -> `@x`. I dind't touch `perlfilter.pod`, since that comes from the Filter dist, which is upstream CPAN.
