Formatter: no line-breaking for long boolean expressions

[edkelly303]

In Gleam 0.12.0

fn something() -> Bool {
  let some_long_variable_name = 1
  let some_other_long_variable_name = 2
  let some_third_long_variable_name = True
  let some_fourth_long_variable_name = False
  some_long_variable_name > some_other_long_variable_name || some_third_long_variable_name && some_fourth_long_variable_name
}

gleam format doesn't seem to attempt to break the the boolean expression over multiple lines, no matter how long it gets.

Not sure what the best place to break would be. Perhaps start by breaking on any || or &&s?

some_long_variable_name > some_other_long_variable_name 
  || some_third_long_variable_name 
  && some_fourth_long_variable_name

Something like that would be good, though I don't mind the exact formatting so much.

I think we could expand it more generally to any binary operations too.

There is also something like this. I also think it looks better if the break is on operators!

Another example:

pub fn to_string(color color: Color) -> String {
  int.to_string(color.red) <> ", " <> int.to_string(color.green) <> ", " <> int.to_string(
    color.blue,
  ) <> ", " <> float.to_string(color.alpha)
}

I think this can be closed now!

Thank you
