No -X flag for unboxed types

[tim]

There doesn't seem to be a separate -X flag for unboxed types; there is one for unboxed tuples, but it seems like Int#, Char# and the rest can only be gotten at with -fglasgow-exts.

-XMagicHash is the answer.

I have no idea where the documentation is, and neither does Google...

[tim]

Oh, well, that was obvious! :-) Section 5.17.12 just describes this flag as "Enable the 'magic hash'," which would have been completely unhelpful to me. So perhaps a documentation change is in order.

Replying to NeilMitchell:

I should like to note that I am now enforcing that all new language extensions registered in Language.Haskell.Extension require haddock documentation including an explanation and examples. Ian was the first victim of my enforcement earlier today when he registered the PackageImports extension. :-)

Hopefully this will help google and hoogle and become a useful reference. Obviously this will require copying out documentation from various places for all the existing extensions.

OK I'll improve the docs.
