Isn't is also possible for someone to copy/paste something with tabs into space-indented code? Isn't is also possible for someone's editor to start off with tab-based indentation by default instead of space-based and mistakenly add the wrong whitespace to the project? As I've said in other parts of this thread, I'm not that worked up about tabs vs. spaces, and I use spaces most of the time. I just don't find this argument for space superiority very convincing. PS: If everyone showed invisible characters in their editors, I think the world would be a better place.
