from Neil Mitchell: add an /edit flag.  The behaviour of winhugs on:

	winhugs.exe /edit filename.hs

is to fire up whichever editor is configured with winhugs and exit
winhugs. The massive advantage of this is a user can set winhugs /edit
as their file handler for editing haskell files, and as they change
the option in winhugs, it gets changed in their system.
