Hello Drew and Michael,

(I'm re-adding guix-devel since Drew original message was not sent there)

(Note: I'm also not subscribed to emacs-devel)

My apologies for this very late feedback!

Sorry I had no time to try to solve my problem following your sugesions, I should be able to test in the following two weeks (I hope).

I'll send you (and emacs-devel) a feedback - possibly with working code - as soon I have updates.

Thank you very much for your feedback and again my apologies to you all for not having replied earlier!

Happy hacking, Gio'
