Check rulings regexp

```
08:47 < Sleaker> !rulings Kozilek, The great distortion
08:47 <+Fryatog> Sleaker: Too many rulings, please request a specific one
08:47 < DoubleFried> !rulings kozilek the great distortion 1
08:47 <+Fryatog> DoubleFried: Duplicate response withheld. (Too many rulings, pleas ...)
08:47 < Sleaker> !1
08:47 < Sleaker> hmm
08:47 < DoubleFried> >:(
08:47 < Sleaker> I think Fry is busted

```

Start with the rulings command and its regexp, using the transcript examples in the issue as reproduction cases. Determine why the requests for “Kozilek, The great distortion” and the numbered variant produce the shown responses. Done means the intended rulings requests are parsed and answered correctly without duplicate or overly broad matches.
