[systemd-devel] [PATCH 1/2] zsh-completion: Move machine listing to autoload

[William Giokas]

Instead of having two different listings of machines, use an autoloaded
function that can be used by other shell completions in the future. It
will also allow editing a single file to change the way machinectl and
systemd-run completion for machines.

No changes, just resent to add on to the previous patch.

There may be more eventually, though.
