Spaces between control structures and parens.

i.e, if(x) { /* blah */ } vs. if (x) { /* blah /* }. I never understood why anyone would use the second style, it's not like it makes the code substantially easier to read (in fact, I think it's aesthetically worse and more distracting), and it wastes line capacity.
