title: "Merge" new file in trunk into a branch
body: <p>This should be trivial and obvious but I can't find any examples of this. (I'm certain that's because I'm just searching for the wrong words.)</p>
  
  <p>I need to merge a file from the trunk of my repository down into a branch. The file is new in the trunk, and not yet in the branch; therefore, the normal way that I know to do a merge just doesn't work.  Thus, I need to get that new file into the branch somehow.</p>
  
  <p>I need to do this selectively with particular files; in other words I don't want to merge down the whole trunk, and I can't even merge a whole changelist.</p>
  
  <p>Thanks for any suggestions.</p>
  
  <p><em>edit</em> &mdash; I realize I can just <em>copy</em> the file from my trunk workspace and <code>svn add</code> it to the branch, but I don't think that's the "right" way to do this.</p>
