There are two unexpected changes in the behavior if I don't add a space token after `\ljudge`.

1. It adds a pair of square brackets as can be seen in the attached screenshots.
2. It uses the default italic shape of `\gla` for the argument of `\nogloss` (which it shouldn't as technically it isn't "glossed".).
