Sorry. I should have explained my explanation better.

svn_fs_predecessor_id (my_id, pool) will return the predecessor ID of my_id,
allocated in pool. But there are at least two places in the code
where we are flying backward through all predecessors, and that
calculation is most efficiently done by modifying a single copy of
my_id in-place rather than allocating from pool which each iteration.
