Rule proposal: forbid superfluous enclosing spaces in same-line jsx components

[giogonzo]

This would produce a warning:

<span> { tab.title } </span>

as it produces 3 <span> DOM nodes (typically not wanted)

This wouldn't:

<span>{ tab.title }</span>

This might be less of an issue with React 15, which claims to produce fewer spans.

[DianaSuvorova]

Oh, I like this proposal. @ljharb this doesn't seem like it has been implemented yet. How about new [jsx-content-spacing]?

[ljharb]

Sure, sounds good.

[whymarrh]

It looks like newer versions of React take care of this, throwing away the extra whitespace.

That said, this would be a useful rule to have if only to enforce consistency—is a PR for this something y'all would consider?

[ljharb]

Yes, i still think this would be a good rule (especially if it autofixed)for consistency’s sake.
