file to have a mode of 0600|umask() instead of just 0600; i.e., the
contents of the files being diffed would leak, even if the wc root dir
was mode 0700 (in which case they don't currently leak).
Is that a problem?
(The comment in svn_io_open_unique_file3() indicates that there's some
historical reason, catering to specific API consumers, for extending the
permissions of the tempfile.)
