As Shawn said, usually. Sometimes we slip too. But it is unnecessary and
anything unnecessary usually makes code harder to read. It is not a big
deal to me.

This isn't the same case, because here we have nested statements, I do think braces should be used here. Java shouldn't even allow "ambigous" syntax like this (first case).

Which is why I think is not that big a deal. The main reason I may leave braces on a non-nested simple statement is becuase I had a debug statement or something like that there, and I might well want to have one again temporarily. Toggling braces on and off (even with eclipse where it requires two-four keypresses) are annoying.
