This is one of those times that a benevolent dicatatorship has its benefits. Programmers have bigger things to deal with than piddly-shit arguments like tabs 'n' spaces and brace style.

The key is that all the tools support whatever people want to do. The solution of "some do this, some do that" is not acceptable if it means that diff doesn't work, for example. In that case, a decision must be made, or tools adapted, or productivity suffers.
