Bug Description

Alpine 2.21 has a performance regression with respect to 2.20. The "folder list" screen, which used to appear instantaneously, can repeatedly take 5 to 10s to appear if one has a lot (a hundred or so) of IMAP folders, and the option quell-empty-directories is set. As this screen needs to be entered every time one changes folder, it is very annoying.

After correspondence with Eduardo Chappa, alpine's current upstream maintainer, he produced the attached one-line patch which fixes the issue. (See also https://repo.or.cz/alpine.git/commit/35f3426203172af028df5a6e39bc6dea2514020d .)

Given that the patch looks simple, and the benefits are considerable, I'd like to suggest updating the 18.04LTS package. (18.04LTS is affected, 16.04LTS has alpine 2.20 so is not.)
