Do you think we should insert a page break before [lex.literal]?

Other than that, looks good to the end of Clause 6.

[iterator.concept.sentinel]: wrapping of sentinel_for is unfortunate. But maybe there's nothing we can do about that without violating local consistency. It's not terrible.

Otherwise, Clause 23 and 24 look OK.

C.5.4 [diff.expr] paragraph 1 has too much vertical whitespace after the second codeblock. Same thing in C.5.2/3 and C.5.3/1 and ... looks like we get bonus vertical space everywhere that a codeblock is followed by one of our bold Annex C labels.

Otherwise, Annexes look OK.

Back matter: split_view::inner-iterator and ::outer-iterator are in the wrong typeface in the index of library names.

Page break added before [lex.literal].

Annex C.5: The extraneous whitespace is a problem. We should try to fix that and re-review. [#4254, applied, needs re-review]

Back matter split view: Fixing separately, #4255.

sentinel-for: see below.

The sentinel-for awkwardness was fixed with a single, local \newpage, no changes outside the two affected pages.

PTAL.
