Date: Mon, 09 Sep 2024 19:42:24 +0100

It appears that share/bash-compltion/bash_completion performs an
`unset -f have' at the end of the script. This means that only the scripts
under /etc/bash_completion.d/ have access to `have', but said directory doesn't
even exist in our case.

That said, `have' is deprecated in favor of `_have' in 2.11, anyway. I have let
upstream libsixel know, but we could work around the issue with a
single-character patch:
