Dear Maintainer,

There are a number of packages that install zsh completions into
/usr/share/zsh/site-functions, but this directory is missing from $fpath
in a fully stock zsh setup.

For reference, $fpath contains /usr/local/share/zsh/site-functions, but
not /usr/share/zsh/site-functions. I see that this change appears to
have been intentional (judging by a changelog entry[1] from 2001), but
I think either zsh should look in this directory by default, or there
needs to be a MBF for packages to move these completion files elsewhere.

Hi,

I submitted MR !11 for review to add /usr/share/zsh/site-functions into
$fpath, here:
https://salsa.debian.org/debian/zsh/-/merge_requests/11

As several maintainers don't have salsa MR notifications on, commenting
here with a link.
