* The phrase "difference between these distances" can either refer to
the conceptual difference (i.e. they hae different semantic meaning)
or to the mathematical difference (i.e. use substraction for the two).
Instead, just remove the sentence since the equations below make it
clear what we're supposed to do here.
* This value is useful in implementing the decoder since we can know
ahead-of-time what size buffer is needed to contain the output of a
transformed word.
* Rather than say "lower 3 bits" in one sentence and "bits 3-5" in
the sentence right after, just consistently use the same convention
and say "0-2" and "3-5".
* Provide exhaustive list of all the ways the last two bytes can be
sourced from.
* Also make a clear connection in this section that there are only 64
context IDs for literals. This is important for the indexing math
in context maps to make sense.
If bit-orderings are to be parsed from left-to-right,
then make the bit-strings left-justified.
If bit-orderings are to be parsed from right-to-left,
then make the bit-strings right-justified.
Section 3.1, which describes how prefix codes work
shows prefix codes that are "left-to-right", which
is better for demonstrating how the work. However,
most of the rest of the document uses a "right-to-left"
convention. We should distinctly say at the end of
section 3.1 that we are switching conventions.
Thus, change the prefix code in section 3.5 to be
"right-to-left" to be consistent with sections 9.1
and 9.2.
Also, change the variable names in section 7.3 to
be consistent with those used in section 10.
Also, change the description of MNIBBLES to be
"MNIBBLES - 4", similar to the convention of saying
"MLEN - 1". Beforehand, the phrase
"If MNIBBLES is 0, then ..." was unclear whether it
meant MNIBBLES before the "plus 4" or after.
Fixed minor whitespacing issues that caused print-out to be slightly
confusing. Biggest change is in section 9.2, where an indent seemed
to indicate that some fields were part of the previous field, when
they were not related.
Also, changed the order that transforms are described in section 8
to match the enumeration values that are explicitly defined in
Appendix B.
