Return back clear divide between each hunk in changes view

All hunks are merged into one view and grey divide is not enough. I provided 2 screenshots that can help to understand the issue.

After the latest updated it starts to hard to understand if the line of code is in this hunk or it already belongs to another one. The previous division was much better.

I propose to use the same divide between hunks of two different files and between hunks of one file. In first case device should be a bit wider.
