Index of library names has cbegin(const C&) and cend(const C&)

Those are not names.

Maybe they should be grouped with the other cbegin and cend names, with "range access" or something as the description. This applies to cbegin(const C&) and cend(const C&) and crbegin(const C&) and crend(const C&).

Also, the first entry in that list (page 1116) is ranges::cbegin which is not at all clear from the index. The discussion in #5831 suggests it should be indexed as cbegin|ranges instead. This applies to all the functions in [range.access], namely ranges::begin, ranges::end, ranges::cbegin, ranges::cend, ranges::rbegin, ranges::rend, ranges::crbegin, ranges::crend, ranges::size, ranges::ssize, ranges::empty, ranges::data, and ranges::cdata.

Combining both suggestions:

cbegin
    basic_stacktrace, 584
    basic_string, 840
    basic_string_view, 823
    containers, 864
    range access, 1105
    ranges, 1116
    tzdb_list, 1528
    unordered associative containers

Locate the source that generates the library-name index and compare the requested naming with the discussion in #5831. Update the cbegin/cend/crbegin/crend entries and the [range.access] entries so their grouping and ranges labeling match the issue; done means the generated index no longer presents signatures as names and identifies the ranges functions clearly.
