While guided with claude (with the Fable 5 model) to find the issue, it 
also suggested me a way to fix it and implemented it with its . I don't 
speak haskell so I let you judge it as I'm unable to do it.
I don't want to contribute to the AI slop things without the help of the 
tool to fix the issue so you'll find the patch and a script to test it 
in the attachements.

The patchs land in hopenpgp-tools on top of master 21d80c8e40cd.
