Hi Robert,

Sorry it took a while to get a response. However, I cannot reproduce
what you are seeing, when trying something like this with svn 1.8.11
(see below).

What version are you using? Maybe this was a bug in older versions of
svn that has since been fixed ... Alternatively, maybe I'm missing
something in my scenario. In that case, can you show a series of steps
or a transcript to reproduce this?

Below is a transcript of what I tried (I tried doing exactly what you
described above). At the end you can see that both branchfile1 (from
branch1) and branchfile2 (from branch2) are merged to trunk.
