Hi Chris,

The other possibly relevant thing -v0 does is suppress the prompt unless
stdin is a tty.  I don't know enough about the tty stuff to know if this is
a problem.  Neil, would this be a problem for your GuiHaskell project if it
used -v0, since it must do something like forking GHCi with stdin set to a
pipe or named socket?

Its entirely irrelevant, GuiHaskell already plays with the output from
GHCi in fairly intimate ways - its not going to pass -v0 but it might
opt to not display things to the user.

Thanks

Neil
