svn_fs_history_prev() and svn_fs_copied_from() question (was: Re: [PATCH] Re: test failure 1.6.14 (svnsync test 29 with bdb; copyfrom))

Yes, that's what I meant, but I see that Philip already committed a fix.

Question to FS people:

Is the svn_fs_history_location(svn_fs_history_prev()) approach
equivalent to the svn_fs_copied_from() approach?
