Applied thanks. "cabal list" is much more useful now.

Originally "cabal list" on it's own listed all packages. That makes a
lot less sense now that we have so many packages and the output for each
is a few lines. I get over 3,000 lines of output now. I wonder what you
think we should do? Perhaps print a message saying to use some search
terms.

"cabal list --simple-output" still makes sense with no search terms
since that's not intended for human consumption.

We should find out what people want the --simple-output for exactly. For
example do they really want substring matching by default or exact like
"ghc-pkg list", or prefix for command completion?
