 For projects with lots of modules, the "modules loaded" message can be
 considerably long. For example:

 {{{

 Distribution.Client.Run, Distribution.Client.Tar,
 Distribution.Client.Types, Distribution.Client.Win32SelfUpgrade,

 It would be nice if there were a way to suppress this message. If there
 already is a way, it would be nice if GHCi mentioned this method when the
 module list gets long.
