title: SVN branch merge
body: <p>I have a question about merging in Subversion. So I have a trunk and then two branches that come from the trunk.  So lets say I have a trunk and then branch A that was created from the trunk and then later branch B was created from the trunk.  </p>
  
  <p>Lets say then that I made changes to B and then changes to the trunk and then merged the trunk changes into B and checked into branch B.  I now want to merge to branch A, not to the trunk.  Is that possible to just merge branch B into branch A?  Or do I first have to merge branch B to the trunk then to branch A?</p>
