Yes. here it is:

    svn copy http://server/repository/product/trunk \
             http://server/repository/product/mods/branch \
             -m "create mod branch."
    svn mkdir http://server/repository/product/mods/branch/subdir \
             -m "create subdirectory."
    svn checkout -N http://server/repository/product/mods/branch
    cd branch
    svn diff -rStartRev

Here is a real-life log:

% svn copy http://svn/test/cko/trunk http://svn/test/cko/mods/svn_crash -m "create mod branch."

Committed revision 1741.
% svn mkdir http://svn/test/cko/mods/svn_crash/subdir -m "create subdirectory."
