When you type /lp group list + TAB it's not correctly autocompleting it. It's becomming info instead of listmembers

Duplicate of #419?

Oh, or you just excluded that in your example?

This is likely because "list" is an alias of the info command.

Aha. It would be great if you can remove the alias :)
