How much work is it to convert these to object_id while at it instead
of char *sha1?
(I think we really dislike introducing new sha1 based code; If it
doesn't sound easy
maybe we can have a static inline wrapper here that just converts oid
to sha1 and
then calls this function?)

Is it possible to line break these functions (c.f. refs.h which I
think has one of
the best styles in the git project. It has long parameter lists, but
still manages
to stay below a reasonable line length) ?

Please be consistent in the use of the extern keyword and omit them at all
times here and above.
