I've had this problem with gpg key selection menus. Customizing a format
probably didn't occur to me when I asked about this in 2018[0], but,
looking at manual.txt, I should try customizing pgp_entry_format.

While changing formats will help mitigating the problem, I expect it to
resurface occasionally. I wonder if there's anything that could be done
in general to avoid truncated lines or to make these readable - either
allowing left-right scroll or having a "line-wrap mode" for indices?

(Or is one of these a mutt feature I haven't learned about yet?)
