The current i18n implementation adds some superfluous newlines at the end of the translation
It can be fixed by removing all newlines in the definition bodies.
I tested the fix with version 5.2.2, I have documented the behavior in the TiddlyWiki at https://framagit.org/wolfmanx/TiddlyWiki-Plugins/-/blob/4f58555b416f98d4398f3b8358950e0c65826c6a/files/dev/i18n-5.2.2.html
