A "static inline" function in a header typically signals that
it is expected to be called from the depths of a performance-
critical loop.  I am not sure if this helper is still in such
a hot path, but I wonder if we can keep it inline and still
teach it to take a "struct repository *r" (or whatever extra
parameter you need) to move these two bits from being global
variables to members of a per-repository structure.
