Neels, this didn't ever work. This is me having started to port some of
the diff code into this new "dirs_same_p" function. I haven't finished
it. I forgot to initialise "target", as you've discovered. There are,
I'm quite sure, other things I haven't yet initialised or coded in this

Next thing I notice is that the test suite says:

$ svn-py-test merge 122
Couldn't find node 'psi.tmp' in expected disk tree
 * Node name: psi.tmp
    Path: __SVN_ROOT_NODE/psi.tmp
    Contents: This is the file 'psi'.

    Properties: {}
    Attributes: {}
    Children: None (node is probably a file)
Dry-run merge altered working copy

Notice the "Dry-run merge altered working copy". It shouldn't do that.
That's a bug I can go looking for. That will be when it is raising tree
conflicts, it wants to generate a notification but it shouldn't store
the conflict information in the WC if it's a dry run.

Do you use IRC? We could chat on #svn-dev if so.
