Data.ByteString candidate 4

Ok, I've tried to encorporate the suggestions from yesterday's discussion. API: http://www.cse.unsw.edu.au/~dons/fps/new/ Src: http://www.cse.unsw.edu.au/~dons/fps.html Changes: * Char functions live in Data.ByteString.Char8 * Improved docs * Anything that needs Data.Char is now in Char8 (lines, words..) * Confirmed that Char8 runs at the same speed as the Word8 layer * isSuffix is about 100x faster. No claims about being a 'Char' packed string library. Don't make claims about encodings. Char8.hs is just a no-op layer over the underlying Data.ByteString Word8 ops. I'm wary of claiming 'PackedString' status, as John says, it isn't a drop in replacement, so Data.ByteString.Char8 seems fine to me. -- Don
