 `protover.c` treats `Link=1 Link=1` and `Link=1` identically, allowing
 duplicate entries without complaint, though it does explicitly check for
 duplicates to avoid double-counting it as two votes for the same version.

 `protover.c` also treats `Link=1 Link=2` and `Link=1-2` the same, while
 the rust implementation of protover treats `Link=1 Link=2` as if it were
 `Link=2`.
