Hmm, ghc doesn't take '-f' as an argument alone... the odd '--' 
interpretation would not be needed if the "runghc -fpath-to-ghc Main.hs" 
syntax were eliminated and only "runghc -f path-to-ghc Main.hs" worked.

Wrappers generally have less-annoying syntax with a fixed amount of 
arguments, e.g. a separate 'runghcf' command or requiring there always 
to be an argument following 'runghc' - but we probably can't do either 
of those here.
