What’s been done here and why:
- src and the most recent variant MUST be identical
- variants may only differ from one another in those areas that warrant the existence of the variants in the first place
- identical means identical! no added/removed whitespace, no reformatting
- yes, some of the code is ugly. you still may not reformat it unless it’s the smallest possible block enclosing the changes you may have made.
- it MUST be possible to find the real differences between variants quickly with phpStorm’s file comparison tool without wading through dozens of false positives caused by added/removed whitespace
- if we don’t meticulously adhere to these rules maintenance of the variants quickly turns into hell on earth
