Formatting

• half the available effort in the ecosystem seems wasted on writing formatters
• claims made by formatters don't check out in practice, e.g. you actually have to think more about formatting when one is in use
• make the ide present each developer's preferred format, with the committed format optimised for resolving conflicts
• nobody needs at most 80 columns, join us in the 21st century
  • a column limit causes similar code to be indented differently which interferes when resolving conflicts
