   Right, I see this as well, thanks.  It is not specific to SVN, though:
   I see the same in a vc-dir buffer showing a Git or Bazaar repository.

Yeah, that was a typo on my side should have been vc-dir.  I started
digging in the code, and ended up in vc-dir-update, but couldn't
really follow the code in there.
