  * Split ShowVersion etc off into a different type to DoInteractive etc
  This fixes trac #1348 (ghci --help gave ghc's help), and also tidies
  things up a bit. Things would be even tidier if the usage.txt files were
  put into a .hs file, so that ShowUsage wouldn't need to be able to find
  the libdir.

    M ./ghc/Main.hs -52 +56
