A wide monitor is for looking at lots of files.
Not dead space because of deep intents and very long variable names.

Although i don't understand the 'indent continuations under "("' rule.
It hides some indents and makes other excessive.
A simple 'double indent' (or half indent) makes code more readable.

A different rule for function definitions would make real sense.
They only need a single indent - the '{' marks the end.
