This reverts commit 4f7ae4815b.
This has come up many times in the past and while going through the fb codebase, there are a few instances where we group array elements logically using empty lines and it's a shame that they are gone.
It turns that our hasNextLine logic needs to be tuned to skip all the trailing comments. The code is not pretty but it does the job. It looks like it fixes a bunch of things in the test cases :)
I made sure that nested inline comments are NOT valid JavaScript
```js
/* /* a */ */
Uncaught SyntaxError: Unexpected token *
```
so it is okay to do a dumb search for */ when you are in a comment
* new_tests
* move_all_clobbered_tests
* remove all the tests that no longer exist
* re-run flow tests
* Move all the flow tests to tests/flow and prettier to tests/
* Move prettier tests to their own folders
* Add jsfmt files
* run prettier snapshot tests
