Single line arrays defined as multi line are expanded even though 'array_auto_expand = false'

[jzenoz]

Hi, not sure if I'm missing something but looking at the TOML spec for arrays:

https://toml.io/en/v1.0.0#array

And using the example there of an array defined across multiple lines but containing only a single line:

integers = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 ]
integers2 = [
  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
]

With .taplo.toml configuration:

[formatting]
array_auto_expand = false
array_auto_collapse = false
compact_arrays = false
column_width = 80

There seems to be no way to disable the expanding of integers2?

No matter what I throw at .taplo.toml the above occurs, if I set array_auto_collapse = true the array is collapsed instead but I want it left alone.

My particular usecase is a configuration like:

data = [
  test, test, test, test, test, test, test, test,
  test, test, test, test, test, test, test, test,
]

Where it's easy to add lines each containing 8 sets of data.
