The length of a macro/string/diversion used for its character count is not the
same thing as its operable length for the purpose of `chop` or `substring`
operations.
This "operable length" should be reported so that surgery on these objects is
more predictable to the non-expert user.
See https://lists.gnu.org/archive/html/groff/2026-03/msg00106.html.
(So far, I've received no feedback on that message despite explicit
solicitation thereof.)
