Hi Gavin,

the --accept option only works for text and property conflicts at the
moment. There are plans to extend this to handle tree conflicts, too.
This depends on wc-ng though so we'll pick up this up again some time
after the 1.7.0 release.

Local changes in the working copy can cause tree conflicts during updates
and merges. But during merges, "local" edits are considered local to
the merge target _branch_ rather than just the working copy.
E.g. if you rename a file on a branch and commit this rename and then
merge an edit for the file at its old location from trunk you'll get a tree
conflict even though the "local" change (rename) has already been committed.

Also, the way you are invoking svn merge seems dubious.
You are doing a 2-URL merge across the entire revision range.
If you use merge-tracking you'd usually avoid 2-URL merges if at all
possible. The way you've run this merge may cause Subversion to apply
changes that were already merged between these branches again which can
lead to spurious conflicts.

You might want to take a look at the merge patterns described in the
new help text for svn merge (e.g. posted here:
If you stick to those patterns chances are your merges will mostly
be conflict-free expect for obvious conflicts.
