Joe Tsai 166edb0287 Minor formatting of Section 9.2. and Section 9.3. 
Many of the fields are copy-pastes of each other, but differ slightly
in placement of words, capitalization, or other random
oddities. This commit makes it so that if you simply do a search
replace on these following passages, you get the same thing:

s/NBLTYPESX/(NBLTYPESI|NBLTYPESL|NBLTYPESD)/g
s/CATEGORY/(insert-and-copy|literal|distance)/g

>>>
   1-11 bits: NBLTYPESX, # of CATEGORY block types, encoded
              with the same variable length code as above

      Prefix code over the block type code alphabet for
         CATEGORY block types, appears only if NBLTYPESX >= 2

      Prefix code over the block count code alphabet for
         CATEGORY block counts, appears only if NBLTYPESX >= 2

      Block count code + Extra bits for first CATEGORY
         block count, appears only if NBLTYPESX >= 2
<<<

>>>
      Block type code for next CATEGORY block type, appears
         only if NBLTYPESX >= 2 and the previous CATEGORY
         block count is zero

      Block count code + extra bits for next CATEGORY
         block count, appears only if NBLTYPESX >= 2 and the
         previous CATEGORY block count is zero

brotli

Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.

The specification of the Brotli Compressed Data Format is defined in the following internet draft: http://www.ietf.org/id/draft-alakuijala-brotli
