Yes, you are right.
BTW: The reason that nobody (from R core, probably not many
people otherwise) has found/mentioned this bug before is not the
use of svn, but the fact that it is much more convenient (and
hence somewhat recommended) to build R outside of its source
directory, and in that case the two *.Rd files that belong to
./tests/ are not removed (from the *build* directory's ./tests/)
