title: Is there any way to run svn log on an entire repository (not just a checkout of trunk) without having to check it out?
body: <p>I've got a Subversion repository that our Atlassian Fisheye instances nearly chokes on because of some accidental commits + backouts ( i.e., someone tagged the entire repository instead of just /trunk, and on more than one occasion).
  So what I want to do is audit the repo for larger-than-average commits, and carry out a dump+load to remove the bad commits using svndumpfilter.
  I'm having a little trouble getting the size of each revision though. I'm nearly there. I've got the following which determines the size of each revision visible using svn log with a trunk checkout:</p>
  
  <pre><code>for r in `svn log -q | grep ^r | cut -d ' ' -f 1 | tr -d r`; 
  do echo "revision $r is " `svn diff -c $r | wc -c` " bytes";
  done
  </code></pre>
  
  <p>However, because the bad commits happened outside the trunk, running svn log on the working copy (of trunk) does not list them.
  Instead I need the functionality of svn log to run repository wide. 
  I COULD check-out the entire repository, but I don't have the days/weeks necessary to check-out all tags+branches.
  Can anyone help me here?</p>
