So do You have any ideas to workaround this behavior?
My main goal to allow user of repository change svn:log message.

Currently only one option I see - create web interface on PHP that use file
interface on host like:
svn propget -r 4 --revprop svn:log file:///mnt/svn/repositories/test1/

Any suggestion, tips?
