 It'd be nice to have a notice displayed when ghci loads a .ghci file,
 something like
 {{{
 rwbarton at morphism:~$ ghci-7.10.1
 GHCi, version 7.10.1: http://www.haskell.org/ghc/  :? for help
 Loaded GHCi configuration from /home/rwbarton/.ghci
 Prelude>
 }}}
 I want this mostly so that we can tell whether people filing ghci bugs
 might have anything relevant in their `.ghci` files.
