This is not about Guix, admittedly. It's about Geiser
I tried to post on the Geiser mailing list 3 times, to no avail
So I'm trying here now. Supposedly Geiser is serving most of the people hacking on Guix, so I hope this is not an outrageously off topic post
When I ask Geiser to open the documentation buffer on some symbol at point, then when pressing q the buffer won't close. A q will appear in the buffer and it will persist.
