I can't reproduce it with r31913 of trunk over file:// or svn://; below
is the script I used. It's based on your script, but this version is
completely self-contained: it creates its own repository, etc.

Starting from your script, it took me about 10 minutes to make the
self-contained version. This is partly because I had the 'kf-doit'
function from http://svn.red-bean.com/repos/kfogel/trunk/.emacs to help
(search for "defun kf-doit" in that file). I mention this because you
might want to keep the kf-doit template around for your own use when
posting reproduction scripts. When a repro script is truly
self-contained, people are much more likely to run it, because then they
know they don't face an arbitrary amount of setup work before they can
run the script.

Anyway, first here's the output of my script, followed by the script
itself. Let me know if the repro recipe I used was wrong.


   Committed revision 1.
   Committed revision 2.
   Checked out revision 2.
   A bar.c
   Adding bar.c
   Transmitting file data .
   Committed revision 3.
   property 'mtime' set on 'bar.c'
   Sending bar.c
   Committed revision 4.
   Committed revision 5.
   A testbranch/bar.c
   Checked out revision 5.
   property 'mtime' set on 'bar.c'
   Sending bar.c
   Transmitting file data .
   Committed revision 6.
   --- Merging r5 through r6 into '.':
   UU bar.c

And the script (not indented, unlike the output above):


# The next line is the only line you should need to adjust.


# Select an access method. If svn://, the svnserve setup is
# handled automagically by this script; but if http://, then
# you'll have to configure it yourself first.
# URL=http://localhost/SOMETHING/repos
# URL=svn://localhost/repos

rm -rf repos trunk testbranch
