Reinstated the closure optimizations in the wheels. They were removed in version 0.0703. It turns out that the closures are necessary to prevent wheels from holding extra copies of their $self references. The extra $self references kept them from self-destructing (Har!) in Flushed states. These closures work better than 0.0702's.
Wheel::FollowTail now wraps its seek() calls in eval blocks, in case the tail being followed belongs to a pipe or otherwise unseekable file.
Cleaned up some ugly style in the places where things changed. Made some other style ugly.
