@codebrainz good point, but _most_ of the filetype names are not translated, only the descriptive ones like "Cascading Stylesheet" see [here](https://github.com/geany/geany/blob/95c0c06cba3dc0d988c2c0a74c5d52fa2e9f3a93...) column [3].
One of the advantages of reading the group names from file is that they can be translated (or not) consistent with the filetype names.
