[PATCH] Mismatch in db/current when hotcopying old FSFS repositories with propchanges

Hi,

I discovered another problem with hotcopy for old FSFS format 1/2 repositories
(apart from those reported in http://svn.haxx.se/dev/archive-2014-01/0089.shtml)
Attempting to hotcopy an old repository with at least one propchange currently
ends up with mismatching node ids in source and destination db/current files.
Here is the patch with a failing test for this problem.

Log message:
[[[
Add a test for the erroneous 'svnadmin hotcopy' behavior for FSFS format 1/2
repositories with at least one propchange. Hotcopying these repositories
currently ends up with mismatching node ids in source and destination
db/current files.

* subversion/tests/cmdline/svnadmin_tests.py
  (fsfs_hotcopy_old_with_propchanges): New test for the erroneous 'svnadmin
    hotcopy' behavior. Marked as XFail.
  (test_list): Add reference to new test.

I did not have time to examine this issue yet, but might be able to do this in
the nearby future.

Thanks and regards,
