I remember some other recent changes to the log function (Related to its strange set of arguments), but I can't find the references here.

svn_client__repos_locations() is a libsvn_client wrapper of svn_ra_get_locations(), which is similar to svn_ra_get_location_segments(), but returns result in a harder to use format. The reason I used that function in my e-mail is because that is the function that implements the real work inside resolve_rev_and_url()
