d87f5d30879aca73fff271c254589fc41a91fdd0 "support for fast O(U)String concatenation using operator+", introducing rtl::ToStringHelper, had intended that length can return an optimistic maximum value if the exact value cannot be determined (e.g., when creating the textual representation of a numerical value only on the fly, not upfront), witness the comments removed now, but never made use of that, always returning precise values from the various rtl::ToStringHelper::length specializations. And then cbe3b2fe0b9d745e22a2bf436ce55141b15f9502 "Avoid conversion warning in O[U]String[Buffer] constructors", not being aware that length could theoretically return an imprecise value, made certain code rely on it always returning a precise value. So clarify the status quo, that length always returns a precise value. (See also the discussion in the comments of abandoned <https://gerrit.libreoffice.org/c/core/+/110129> "Drop obsolete comments".)
