the last version of -current that was 1.3x from which both 1.4A and
the netbsd-1-4 (release) branch sprang is the version of the source
tree tagged netbsd-1-4-base.
I dunno which letter it had, but that's not specific enough to
describe the very last version anyway.

Right. There is _no_ 'version name' (please don't say tag 8-) to name
that common ancestor, only the CVS tag.
[ to add back some context that you trimmed... ]
1.4A is netbsd-1-4-base + some set "X" of changes.
1.4B is netbsd-1-4-base + some set "Y" of changes.
1.4 is netbsd-1-4-base + some set "Z" of changes.
X is a proper subset of Y.
That is the only relationship between those sets of changes.

Yes. In other words, no well defined relationship. Z is not a subset
of X or Y, it's not a superset of either of them, it's not equal to
either of them, and in fact it's not even a sub- or superset of or
equal to X + Y.
("ableit retrofitted" applies to both "some members of X" and "some
members of Y")
