We do not allow anything elaborate like "refs/tags/release-*" but we
still allow "refs/tags/" and "refs/heads/" by listing them together,
and because these are only prefixes, whitespace is a reasonable list
separator as they cannot appear anywhere in a refname. OK.
Why is this "core"? I thought this was more about receive-pack;
even if this is going to be extended to upload-pack's negotiation,
"core" is way too wide a hierarchy. We have "transport.*" for
things like this, no?
The exact same comment applies to 2/3, of course.
