Sorry that should have been `buffer'.

If the file is indeed read-only, then everything works as expected,
but the VC code also tries to make the buffer read-only when the file
is locked by someone else and yet is writable.  This can happen either
because the user is using group-permissions in unusual ways or because
VC is confused and doesn't realize the the current user and the user
holding the lock are one and the same.
