`cabal fetch` formats dependency solver errors incorrectly

[grayjay]

The fetch command prints dependency solver errors in quotes:

$ cabal fetch cabal-install-99
Warning: this is a debug build of cabal-install with assertions enabled.

The error messages should have the same formatting as in the install command:

$ cabal install cabal-install-99

Looks suspiciously like someone used show or print.
