Wonderful. Thanks once more.

FYI: There was a tiny bug introduced by the process, which I fixed here. This only affected building the documentation, which is probably how it fell under the radar. I don’t know whether this was a human error or introduced by the linter. In the latter case, it’s probably a bug worth reporting.

Oops, sorry! That was a human error, I'm afraid.. I did a quick line sort (with vim) in the list and didn't notice there was a missing comma :(

Thanks for fixing it! I'll remember to check the docs build too next time.

For what it's worth

   "something",
   "something else"
   " and this",

is not a syntax error or anything like that, since it just performs implicit string concatenation between line 2 and 3. There's a ruff check for that if you want to turn it on: https://docs.astral.sh/ruff/rules/multi-line-implicit-string-concatenation/.

I am aware – except for the Ruff check, which I don’t think is necessary (but I also do not oppose).
