  Hmmm, my mistake, I think.  I thought it was general svn URL syntax, but it seems to be a special form just for the diff and merge commands.

  Still, if you think the logically right thing to do is to always use @HEAD, then the whole @ bit can be omitted, and it could just be svn_url=".../trunk" and svn_url=".../tags/2.0.1/", since HEAD is the implied revision in those cases.

  The reason I prefer @REV when looking at tags is that tags can be deleted.  In such cases, trying to look at them @HEAD does not work, but trying to look at them at @REV, where REV is a revision at which they existed, does.  But that's moot since it seems it won't work :)
