Currently this message is displayed for (at least) three different types of error. There should be separate messages for each scenario.
Done in r45865.
Nice. Do you think 'revdelete-nologid-text' should use {{plural}} in some fashion? Or since hiding multiple entries at once is not (currently) supported, should it just be singular?
AFAICT, the only way you'll actually ever see that message is by manually messing with the URL to add a logid that doesn't exist or some sort of strange situation where the log entry is manually deleted from the database between the time Special:Log is opened and the show/hide link is clicked. plural support might be nice, but probably not necessary.
