Don't do the PAGER thing

In my set up, PAGER is set to "" so that I can run git commands in emacs and have them work properly.

I could in theory set my PAGER to "cat", but it's nicer to just have the PAGER thing be more directly controlled via explicit piping.

i.e:  ghc-core Foo.hs |less -R

You could always use a shell alias for the pipe-into behavior.

It took me some debugging/confusion to figure out that "ghc-core" just silently failing was caused by the PAGER thing.
