This constant appears another place, too. It might make sense to define
a constant `REF_STORE_ALL_CAPABILITIES` in `refs-internal.h` alongside
the individual bit values.
If you prefer not to, please at least declare this variable `const` to
spare the reader the trouble of looking to see whether it is modified
before it is used.
Otherwise, looks fine to me.
