JOSM removes "newline" characters \n from inscription when editing nodes

[scyyy]

I was adding operator:wikidata tags to some nodes (e.g. ​https://www.openstreetmap.org/node/12344145506). These nodes have an inscription= tag created by iD that's using \n in its value to signify line breaks. According to ​https://wiki.openstreetmap.org/wiki/Key:inscription, this is a valid usage.

However, after uploading the changes via JOSM (changeset ​https://www.openstreetmap.org/changeset/159245848), the inscriptions all lost their \n linebreaks. I'm not exactly sure whether JOSM converted them to actual newline characters (instead of a backslash followed by an n) or replaced them with spaces. In any case, it should not do that, especially not in a totally silent way when my edit didn't even change the tag value at all. I'm glad that I saw this happening and was able to revert it; pretty sure that not everyone would.

Adding the status report manually because the "Report bug" button would send me to Debian's bug tracker, but I don't assume this is Debian-specific behavior. Let me know if you need more information, and thanks for looking into this.
