    vcview: Make temporary version control files un-writable
    
    A version control diff is a diff of a local file vs the contents
    of a repository.  A user can't edit the repository directly, so they
    shouldn't be able to edit the temporary file representing the repository
    either.  This also prevents a user from accidentally modifying a
    temporary version control file in /tmp, saving it (thinking they were
    saving the "real", working copy), then having it be automatically
    removed when closing meld.
