Not directly related to the PR/translation itself: what's was your feeling/experience when translating this file now #233 and #241 have been merged? Any feedback?

I haven't really used the .local.dic sorting yet because it wasn't an effort for me to put the new exceptions in the right place, but I have no doubt it's super useful in general and will prevent a lot of careless mistakes in the long run.
The pre-commit hook is going to be life-saving. One thing I noticed is I have the following message:

.remarkignore was not in your staged files, so we have added it for you.

...when I amend my commit, but aside from the message itself it doesn't have any unwanted effect.

Just to let you know I have merged these commits into your first one
