Language help files in recent versions

I've noticed in recent versions (from git), when I do something like ":help 'auti<tab>", I'll see something like this:

:help 'auto
'autoread' 'autosave'@en 'autochdir'@en 'autoprint'@en 'autowrite'@en 'autoindent'@en 'autowriteall'@en
:help 'auto

Are those @en's supposed to be there? It didn't used to show them. Should I ask this on vim-dev instead?
