* Allow JSX lines to be recombined
* Add test case for `<br />` breaking expression
* Fix issue where JSX whitespace could be dropped
* Newlines were incorrectly being preserved when JSX contained text
I didn't intend for putting parenthesis there in the first place but it slept through. Since it was going to trigger a ton of changes I held up changing it, but I feel like we need to do it sooner than later otherwise we're not going to be able to do it. A lot of people writing functional components are going to be very happy about this change :)
This commit updates `npm run format:all` to not only format .js files in
src/ and bin/, but also tests_config/ and scripts/, as well as all
jsfmt.spec.js files.
It also includes the result of running `npm run format:all`, except
changes to src/ and bin/.
