This also happens if you have extra-verbose but no group-name and you
get both command & parameter completions in the same list:

% v
vared  -- vared
vim      -- Vi IMproved, a programmer's text editor
vim    -- vim
vimdiff  -- edit two, three or four versions of a file with Vim and
show differences
vimtutor -- the Vim tutor
vis      -- display non-printable characters in a visual format
vm_stat  -- show Mach virtual memory statistics
vmmap    -- Display the virtual memory regions allocated in a process
vtool    -- Mach-O version number utility
vared           venc_data_dump  vi              view            visualinfo
