This looks more like add_pseudoref_entries() given that the general
direction is to have an "allow" list of pseudo refs (at this point
after the previous step of the series, is_pseudoref_syntax() is the
is_pseudoref() function, and uses ends_with("_HEAD") as a mere
optimization to avoid listing all the possible pseudo refs that
exists or will be added in the future whose name ends with "_HEAD").

Other than the naming, I think these two steps make sense.

Thanks.
