Just guessing here but Subversion does not have any idea about the concepts
of trunk and branches. So what you see is that Subversion optimizes accesses
by keeping HEAD undeltified be the file in a branch or on trunk.

Thinking about why the Subversion community never saw this problem before:
We remove dead branches. Therefore the tip of the branch no longer is in
HEAD and thus can be stored as delta.
