Hello, Teraboll.

Thanks for this.

Since most of your latest changesets contain the same obscure "error correction" title, I would like to suggest that you would use something more descriptive in the future.

The reason is that we see lots of strange edits every day (and even some vandalism) under innocuous-sounding titles.  It is therefore important that changeset titles clearly describe the content.

Your edit here is fine.  If I understand correctly, past building imports had unnecessarily created new nodes instead of reusing existing ones, and this is what you are currently cleaning up, right?

Have a nice day.
