The backup should just skip any unreadable directories (so a 0
directory won't be backed up, but shouldn't mess anything else up
either).  The --change-source-perms option was removed because it
wasn't error-safe:  if an rdiff-backup session failed right after the
permissions on a source directory were changed, they could stay that
way permanently (after all, even if rdiff-backup tried to change them
back the next session, who's to say that the user or another process
had intentionally switched them in the meantime?).  So anyway, it
seemed to conflict with the idea that a backup program really
shouldn't be destroying the source data.  (High standards eh?)

Yes, 0 vs non-zero (usually, but not necessarily 1).  Adding to man
page now.
