[Haskell-cafe] Using multiple versions of the Haskell Platform on Windows

[Yitzchak Gale]

Thanks. We also should improve on what the installer
does to the PATH in previous of existing HP installations.
And provide a similar utility for choosing the default HP
(not just in the current window) by changing the PATH
in ther registry.

I took a stab at this last one, but didn't have it working
yet due to getting registry permissions wrong. You can
see it in older commits in the win-hp-path repo on github.

Neil Mitchell pointed out in the reddit thread that this
utility actually isn't specific to HP - it can be used to
choose between different GHC versions regardless of
whether they are part of HP installations. But that is not
for the faint of heart.

Regards,
Yitz
