A creating command exited 0 without creating anything.

`tmux -S <dir>/missing/sock new-session ...` prints `error creating
<path> (No such file or directory)` on stderr and exits 0 with empty
stdout: exit 0 usually means the command ran, so this is its own
variant rather than [`Self::CommandFailed`], which would print the
exit code as `Some(0)` beside the word "rejected" -- a contradiction
-- and rather than [`Self::AfterEffect`], which would claim an
effect that never happened.
