As outlined in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=279503 there are
various ways we are listing stable/N and releng/N.n - sometimes with numbers,
sometimes not.
I'm suggesting to migrate everything into one common format. What I have not
resolved yet (and would appreciate feedback on): there are still numerous
examples with i.e. stable/13 (I updated from stable/12). It would make sense to
simply change them all into a stable/N and releng/N.n format.
Ed made the point that he received issue reports for people misunderstanding the
placeholder syntax, so maybe it makes sense to leave a handful of examples with
numbers?
