A syntax highlighting plugin <disclaimer>which I co-maintain</disclaimer>
would highlight the two cases differently:

[[[
% tests/generate.zsh 'mv *(.) foo/' main users-27486a
⋮
BUFFER=$'mv *(.) foo/'

expected_region_highlight=(
  '1 2 command' # mv
  '4 7 default' # *(.)
  '4 4 globbing' # *
  '9 12 default' # foo/
)
% tests/generate.zsh 'mv *() bar/' main users-27486b
⋮
BUFFER=$'mv *() bar/'

expected_region_highlight=(
  '1 2 command' # mv
  '4 4 default' # *
  '4 4 globbing' # *
  '5 6 reserved-word' # ()
  '8 11 unknown-token' # bar/
)
% 
]]]

So, in the second case you'd see the «()» in yellow and the directory
name in red (or, if AUTO_CD is set, green).
