As described here http://svn.haxx.se/dev/archive-2013-01/0567.shtml , merge
notifications are a bit off when incoming changes land in a subtree which the
merger doesn't have access to.
Given this authz:
[[[
[merge_authz_tests-4:/A/C]
jrandom=
[merge_authz_tests-4:/]
jrandom=rw
]]]
### And these changes to merge from ^/A to branch:
>svn diff --summarize ^^/A -r1:3
