Error in the help regarding option with multiple params types (Number, Array)

For example, the gh pr and gh is accept arrays of numbers.

Then in the options we have:
```'number'   : [Number, Array]```

This is what I see on the help:
```
gh    ➜  pr, pull-request Provides a set of util commands to work with Pull Requests.
gh         -a, --all
gh         -b, --branch (String)
gh         -B, --browser
gh         -C, --close
gh         -c, --comment (String)
gh         -D, --description (String)
gh         -d, --detailed
gh         -f, --fetch
gh         --fwd (String)
gh         -i, --issue (Number)
gh         -l, --list
gh         -M, --merge
gh         -n, --number (function Number() { [native code] },function Array() { [native code] })
gh         -o, --open
gh         -R, --rebase
gh         --remote (String)
gh         -r, --repo (String)
gh         -S, --state (open,closed)
gh         -s, --submit (String)
gh         -t, --title (String)
gh         -u, --user (String)
```


Notice the
```
gh         -n, --number (function Number() { [native code] },function Array() { [native code] })
```

Is this only happening with me or with you also?
