Steps to reproduce:
Unknown
Actual result:
Viewing https://en.wikipedia.org/w/index.php?title=Special:Contributions&offset=&limit=20&target=DannyS712 (when the edit in question was the most recent edit the user made):
```
lang=html, name=Rollback link
<span class="mw-rollback-link"><a href="/w/index.php?title=Frank_Finn_(footballer)&action=rollback&from=DannyS712&token=ed35e205c234c2ce469750f6fd8274735e3fefb0%2B%5C" title=""Rollback" reverts the last contributor's edit(s) to this page in one click." data-mw="interface">rollback: 0 edits</a></span>
```
`[rollback: 0 edits]` is the text shown
Note: This is the content of the `rollbacklinkcount` message; enwiki has a custom definition it: `rollback: $1 {{PLURAL:$1|edit|edits}}`
Expected result:
A message to rollback 0 edits is never shown, since rollback reverts one or more edits
