* Make hGetContents throw an exception if an error is encountered
Ignore-this: 9f7a7176193eab25c9daaacd9261f2de
Strictly speaking this breaks Haskell 98 compatibility, which requires
hGetContents to just end the lazy stream silently if an error is
encountered. However, for a few reasons we think it will make
everyone's life a bit easier if we make this change
1. Errors will be a lot more common in GHC 6.12.1, in the form
of Unicode decoding errors.
2. When Haskell 98 was designed, we didn't know how to throw
exceptions from inside lazy I/O, but now we do.
3. If anyone is actually relying on the previous behaviour, their
code is arguably broken.
