It should be interpreted as "git pull branchname" does, or at least as
close as possible.
Another non-working example is with:
remote.origin.fetch=+master:refs/remotes/origin/master
branch.master.merge=refs/heads/master
so it looks like that both have to match for remote_find_tracking to
work (and in this case "git fetch" also works ok).
I suppose that remote_find_tracking should DWIM: build the full ref
prepending refs/ and heads/, as necessary.

They are currently allowed (fetch/pull) since a long time, and it is
not only this config, but also remote.<remote>.fetch (see above).
In b888d61 (Make fetch a builtin, 2007-09-10):

[...]
This changes a few small bits of behavior:
branch.<name>.merge is parsed as if it were the lhs of a fetch
refspec, and does not have to exactly match the actual lhs of a
refspec, so long as it is a valid abbreviation for the same ref.

With tags yes, but full qualified.
