Recent Brian2 update PR broke benchmark scripts

[denisalevi]

I just realized that the Brian2 update (#249 ) broke the benchmark scripts because some changes in brian2.diff got lost.

See my comment here: #249 (comment)

I wonder whether it is actually worth fixing this in brian2.diff – maybe it is just simpler to move the test/features to brian2cuda in the "correctly diffed" version and adapt the scripts to use these instead of the ones from brian2? We could then get rid of brian2.diff completely, which would also make future updates easier. You already proposed this (#249 (comment)) but considered it wouldn't be worth the effort right now. But maybe the effort estimation just changed and it might be easier than fixing brian2.diff... 😬 ?
