 Right now, {{{cabal fetch}}} fetches all missing dependencies of a package
 along with its source.

 In some cases, in particular when studying code, those dependencies are
 not useful. It would be nice to have an option, say {{{--no-deps}}} to
 fetch just the specified packages.

 (This is related to {{{cabal unpack}}} -- see #390.)
