We cannot calculate them even over HTTPv2 in case of switched paths
(or file externals). Bert implemented some heuristic in r1142065, but
as any heuristic method. Really stable way to fix the problem is to
include property with repos relative path to update report.
The problem that old code actually didn't work: X-SVN-VR-Base request
header was simply ignored by server (see r1141845).
