And you didn't read what I wrote ;-)

svn merge trunk@HEAD feature_branch@HEAD trunk_wc
  (ignore my dodgy syntax)
- WC = trunk
- Merge
  From: Trunk @ HEAD
  To : feature_branch @ HEAD

This example (or one close to it) is given in the SVN book; it then goes
on to say that it will probably not do what you want it to, but it then
doesn't give an example of why you might want to use it.

The problem is that the users are getting confused between to/from and
source/dest. They want to merge branch into trunk, and they are setting
From: Branch @ HEAD
To : Trunk @ HEAD
which is not what they want.
