When the same operator is used consecutively, support to append the operatior at the end

[normidar]

now, dart support

var lst = [
  a,
  b,
];

but not supprt

var lst = 
  a &&
  b &&;

or

if ( a &&
b &&) {
.....
}

I think this feature is useful.

If I have a statement :

if (
cond1 &&
cond2 &&
cond3 &&
cond4 &&
cond5 &&
) {
....
}

I can comment-out anywhere.

What about <<, >>, >>>, &, ^, |, *, /, ~/, % +, -, as, is, is!, .., =, *=, /=, +=, -=, &=, ^=, <<=, >>=, ??=, ~/=, |=, %=, ==, != and ||? I suspect not too many people will frequently write large if statements, always followed by the same operator and want to break the last line. I would prefer , as a consistent approach to break the line before ending the if statement/expression. Considering issue #69 is on hold for about 5 years, I believe this will be time-consuming to implement.
