Should we keep the two texts '32-bit' versus '32 bits'? (and others 16, 64, ... )

git grep -nE '([0-9]-bit|[0-9] bit)' '*.md' shows them.

"N-bit" is a compound modifier, and is typically hyphenated; we should consistently do so, and, in 75d3646, I've fixed all the occurrences that I found, along with some occurrences of "N octet".

"N bits" isn't a compound modifier, it's a phrase with a count of bits (and "1 bit" is also not a compound modifier if it doesn't modify something, as in "a 1-bit field").

So "N bit", when used as a modifier, should be hyphenated; "N bits" and "1 bit", when not used as a modifier, shouldn't be.
