If we _were_ doing the inline function, I would actually prefer:

        static inline ref_is_head(const char *ref)
        {
		return !prefixcmp(ref, PATH_REFS_HEADS);
        }

But at least to me,

	if (!prefixcmp(head, PATH_REFS_HEADS))
		head += strlen(PATH_REFS_HEADS);

is easier to follow than:

        if (ref_is_head(head))
                head += STRLEN_PATH_REFS_HEADS;
