I prefer keeping the conditional statement separate from the condition, but
either way works. One thing I've noticed though is that one line if statements
are difficult to debug in a debugger because there is no way to tell by watching
the current debug line whether the conditional statement was executed or not.
For that reason I use a two line if. Of course, rumor has it that real
programmers don't use debuggers.... :)

I would rather use the extra lines for two line if statements, then make up for
that used space by avoiding unnecessary braces.
