OK.  Then it is OK to limit notes.<ref>.mergestrategy so that <ref>
refers to what comes after refs/notes/, because we will not allow
merging to happen outside the hierarchy.

If you are planning to break that promise, however, <ref> must be
always spelled fully (i.e. with refs/notes/ prefix for those inside
the hierarchy) to avoid ambiguity.  Otherwise it will be hard to
interpret a configuration that does something like this (note that
these could come from multiple places, e.g. $HOME/.gitconfig and
$GIT_DIR/config):

    [notes "commits"]
        mergestrategy = concatenate
    [notes "notes/commits"]
        mergestrategy = cat_sort_uniq
    [notes "refs/notes/commits"]
        mergestrategy = overwrite

The three entries in the above example obviously are all meant to
refer to the same refs/notes/commits notes tree, and the usual "last
one wins" rule should apply.  But with the recent git_config_get_*()
interface, you cannot tell which one among them was given the last,
overriding the previous entries.
