(Just to close off this thread) I fixed this bug myself in r956119 by adding
a new macro which combines the check for SVN_ERR_WC_NOT_WORKING_COPY and
SVN_ERR_WC_UPGRADE_REQUIRED, and then made use of the macro in many places
where the former of those errors was checked. Don't worry -- Subversion
still tells you if you try to operate directly on a pre-1.7 working copy
that you need to upgrade. But crawls up the parent chain now stop where
they used to (and should): at the first directory that's not a (valid)
working copy.
