* Revert "Remove mutation in `printBinaryishExpressions` (#1067)"
This reverts commit e7312ad7b2.
* Revert "Make it clear what parser was used in each snapshot (#1068)"
This reverts commit 4f7ae4815b.
It seems like precedence for this combination of operators is very unclear to people (myself included) and consistently adding parenthesis there would be good.
Fixes#773
The original motivation for this change is trying to fix#560 where the comment was attached to the JSXText node instead of the JSXExpressionContainer because it used the globalPrecedingNode. In general, I don't think that it is very safe to attach a comment to a random node just because it happened to be before.
I tried to delete the globalPrecedingNode codepath and I think that it actually improves the results. I'll add inline comments in the pull request to explain the various changes.
Fixes#560
This was introduced by #314 where `line` should have been `softline`. By the way, I was going to propose renaming `line` to `line_or_space` and `softline` to `line_or_nothing` which should make it more explicit what is going on.
Fixes#461
