[Formatting] Operators at the beginning of lines

[Followin]

This should be an option/default behavior:

Before

var a = '123354535435' + '2342423153';

After (if it's too long to fit in a line)

var a = 
    '123354535435'
    + '2342423153';

instead of

var a = 
    '123354535435' +
    '2342423153';

Same goes for all of the conditional operators like && and ||

Learned about Rome today. Impressed by the speed and defaults. 🚀

Not having support for breaking before binary operators is a blocker for me.
To quote Guide van Rossum: "For decades the recommended style was to break after binary operators. But this can hurt readability in two ways [...]".

This new style is the default in Python for example; see PEP 8 and black formatter.
