Typing a second slash command went dead whenever the message started with
one: `/work /cle` offered nothing while `do /work then /cle` completed
fine, which reads as an intermittent glitch rather than a rule.
Only the first slash can be an invocation, so detect the inline shape
first. The leading-command branch claimed the whole line and handed it to
the backend's completer, which has nothing to say about a slash sitting in
a command's argument tail. The inline trigger requires a whitespace-preceded
slash at the caret, so ordinary argument completion (`/cron ad`,
`/personality alic`) is untouched — it fires only where completion was
already dead.
