Comment(by simonmar):
I find it weird that `-no-user-package-db` affects the "initial stack",
but `-user-package-db` appends the user db to the final stack. So e.g.
`-user-package-db -no-user-package-db` does not do what you expect.
So I see two alternatives. One is to modify my proposal to take into
account `GHC_PACKAGE_PATH`: just initialise the stack from
`GHC_PACKAGE_PATH` before processing the arguments, defaulting to
`[global,user]` if `GHC_PACKAGE_PATH` is not set.
The other alternative is to keep the concept of the "initial stack", but
make `-user-package-db` and `-global-package-db` just the inverses of
`-no-user-package-db` and `-no-global-package-db` respectively. I'd be ok
with that too.
