As part of a code standards document I wrote awhile back, I enforce \"you must always use braces for loops and/or conditional code blocks, even (especially) if they\'re only one
I think the important thing about braces is that they very definitely express the intent of the programmer. You should not have to infer intent from indentation.
That said, I like the single-line returns and continues suggested by Gus. The intent is obvious, and it is cleaner and easier to read.
