Are your referring to the fact that Make requires tabs to indent blocks of commands? It's not even whitespace in that case - Makefile treats the character as a prefix. Sounds like it would be even worse if it required 4 spaces... I actually see Make's use of tabs a great example of why they make more sense for indentation, especially when it matters. 1 \t => +1 level of indentation. No guessing the number of spaces and praying it stays consistent throughout the file.
