automate braceless return substitution for long lines

Per [bjorn3][https://github.com/bjorn3] suggestion resolves cases where
an early return is moved to a separate line due to line width formatting.

This setting changes
```
if (a very long condition) return;
```
to
```
if (a very long
    condition) {
  return;
}
```
while keeping
```
if (short) return;
```
as is.

In pathological cases this may cause `npm run fix` not to fix formatting
in one go and may require running it twice.
