What
/focus is now marked as terminal-oriented.
Separately, slash-command completion, the suggestions you see as you type a command after /, now keeps two lists: plain command names, and names that include a prefix. Based on what you have typed, completion can suggest the plain name in place of the prefixed one.
Why
Completion can match a command whether you type its short name or its full prefixed name.
