What is the proposal on how you would normalise this? It would be good to know so that I can be consistent with cargo-lock2rpmprovides in the provides lines we generate.

I'd replace - by _ and that's it.

0.10.2+wasi-snapshot-preview1 would become 0.10.2+wasi_snapshot_preview1in this case? Or would you also normalise the + to a -?

We cannot use - for anything.

I created this PR that should fix this issue. Feel free to give any feedback.

#148 was merged, this should be fine now.
