Glossary recognation issue with "-"

[NekoJonez]

Mte90/GlotDict#275

Basically, take add-on for example. If you add "add" to a glossary, for that word, the first part of the word would be recognized as a glossary word.

This can lead to mistakes and very awkward translations. Its a fix to add add-on to the glossary... But this is just one example and not everybody has access to adding things to the glossary.
