   * Add cabal fetch --no-deps and --dry-run flags
   Allows fetching one or more packages but without fetching their
   dependencies and thus not requiring that a consistent install plan
   can be found. On the other hand --no-deps means that there is no
   guarantee that the fetched packages can actually be installed.
 }}}

 Leaving this open for the moment since it would be nice to add a message
 to tell people when normal `cabal fetch` fails that they can avoid the
 deps, or use `cabal unpack` etc.
