I was just going to open an issue about this and noticed this one :).

Besides the fact that it appears to always be added, I'm seeing it get added multiple times, once per RSpec.configure block (I commonly use RSpec.configure in multiple files).

I'm aware of it, but it's difficult for Transpec to determine which RSpec.configure is the main one.

I'm aware of it, but it's difficult for Transpec to determine which RSpec.configure is the main one.

Putting on only one configuration block that isn't the main one is better than putting it on all of them, IMO. Also, maybe this could work as a simple heuristic when doing runtime analysis? Pick whichever RSpec.configure block is run first as the main one?

It seems reasonable. I'll try.
