title: Is it possible to get svn client debug output?
body: <p>I'm looking to enable extremely verbose logging output in the svn client specifically for the task of resolving botched merges.</p>
  
  <p>The problem I'm facing currently is merging from trunk into my feature branch brings in no new changes, but a diff of the two HEADs reveals outstanding unmerged work.</p>
  
  <p>Generally I'd think this means that the mergeinfo has been messed up, or there is some mergeinfo deeper in the project directory structure that is causing issues. However in this case I've cleaned all the mergeinfo properties and manually ensured the root of the feature branch's mergeinfo does not contain the revisions that are on the head of trunk which I'm attempting to merge in.</p>
  
  <p>For this task and others I'm looking to be able to enable an SVN debug log which literally shows me stuff like:</p>
  
  <ul>
  <li>Attempting to merge in revision XXX from https:.... to working copy
  <ul>
  <li>Skipped, already merged in</li>
  </ul></li>
  <li>Attempting...</li>
  </ul>
  
  <p>I was looking at recompiling the svn client with some sort of compile time flags to indicate logging verbosity but was not getting anywhere. Does anyone have any pointers on how to get more information from SVN Client? (command line, linux).</p>
