I initially thought it didn't but it turns out that I made a typo. That
method works for pulling from a single tree using the svn repo tree
hierarchy. However, it doesn't seem to work for creating a working copy
that contains dirs from multiple branches/tags. How would you create a
working copy that looks like:
        wc/mod1 <-- trunk/mod1
        wc/mod2 <-- branches/branch1/mod2
        wc/mod3 <-- tags/tag2/mod3
that svn will see as a single working copy?

That goes back to the question I asked in the previous email. Is there
a way to pull multiple "toplevel" dirs without using multiple commands?
Subversion seems to (wrongly) assume that a working copy will consist of
a directory structure that can be obtained by pulling a single
directory. Using the 'svn up -N' method works around the issue for
directories that live as direct subdir of the toplevel dir but I don't
immediately see how it can be extended to any branch/tag directory (or
