We're soon going to change the type of our mailmap into an opaque struct
so we can add features and improve performance. When we do so, it won't
be possible for users to inspect its internals to determine how many
items are present, so let's introduce a function that lets users inquire
how many objects are in the mailmap and use it where we want this
information.
