Summary:
* "Wrapping"/"Binary Operator" = "If Long" doesn't work as expected.
* "Wrapping"/"Wrap After Binary Operator" behave as inverted on existent line break. So user cannot change formatting to right because auto-format will broke it/

Examples:
Suppose "Tabs And Indents"/"Right margin" = 20,
"Wrapping"/"Binary Operators" = "If Long" and "Wrap After Binary Operator" is unchecked.

--- 1 ---
Before ('|' - margin position):
$long_expr == $other|_long_expr;

After:
$long_expr == $other_long_expr;

Expected:
$long_expr 
        == $other_long_expr;

However when "Wrapping"/"Binary Operators" = "Always" it work as expected.

--- 2 ---
Before:
$long_expr 
        == $other_long_expr;

After:
$long_expr == $other_long_expr;

Expected:
$long_expr 
        == $other_long_expr;

However on next code it don't change formatting (remember "Wrapping"/"Wrap After Binary Operator" is unchecked):
$long_expr ==
        $other_long_expr;

And when I set "Wrapping"/"Binary Operators" = "Always" it works as expected.

--- 3 ---
When "Wrapping"/"Wrap After Binary Operator" is checked

Before:
$long_expr == 
        $other_long_expr;

After:
$long_expr == $other_long_expr;

Expected:
$long_expr == 
        $other_long_expr;

However on next code it don't change formatting:
$long_expr
        == $other_long_expr;

--- 4 ---
Same behaviour for ternary operator. 
Before:
$condition ? $long_e|xpr : $other_long_expr;

After:
$condition ? $long_expr
                    : $other_long_expr;

Expected:
$condition 
        ? $long_expr
        : $other_long_expr;

--- 5 ---
Except there are no "Wrap After" option which would prevent next code unchanged.

Before:
$condition 
        ? $long_expr
        : $other_long_expr;

After:
$condition ? $long_expr
                    : $other_long_expr;

Expected:
$condition 
        ? $long_expr
        : $other_long_expr;
