From gregmarr's review of #5630:
- alloc_nodes() gives a request of half of the next chunk or more a chunk
of its own, so that the rest of the current chunk stays available for
smaller requests instead of being abandoned.
- The comments on edit_state, append_text(), and reserve_moved() say that
views stay valid across every edit (not just the first), that n is 0 for
empty strings, and why both capacities are checked.
- The architecture page names flag bits 3, 4, and 5 (linked) separately
and says that a discarded view has no node; erase.md rewords overload 3
and says why it never throws invalid_iterator.202.
