My bad.  Please ignore the question.

The values essentially come from `version-control', where what's being decided
is for all files.  Since this is only for the bookmark file there is not a big
need for offering both `nil' and `never' values.  I think that is what confused
me somehow.

The only real choices for the bookmark file are using numbered or unnumbered
backups, and whether to let `version-control' decide that: i.e., values `t',
`never', and `nospecial'.

`nil' (vs `t') has meaning here only if you somehow already had a numbered
backup for the bookmark file.  `nil' makes sense for `version-control', however,
because that option governs multiple files.

If the value here is `nospecial' and the `version-control' value is `nil', then
you get the same result as `never' for the bookmark file, unless you previously
customized `b-v-c' to `t'.  I think that's the case that I was finding
confusing.  I was wondering how, in that case, a user might have created a
numbered backup in the first place.

It's not important.  Sorry for the noise.
