That's exactly the reason. Many people do the same thing in Perl, too, considering we use the same assignment and equals operators.

Personally, I try to remember to do so during an initial version and I might make the swap if I'm already rewriting or refactoring code. I don't go through existing, working code looking for that and making the change. Changing something that's not in error is error prone in itself, and why take the time?

Update: I completely missed the braces added at first. That's a good change, and it is another one I try to stick to in C and PHP (which have the same single-statement rule for conditionals) for initial versions. Still, unless I have some reason to change working code, I won't. When I change the code around that section, I'd probably go ahead and add the braces whether or not I was adding another statement. I wouldn't just go into the source and add the braces and not change anything else.

As an aside, the "blue" language (as opposed to the "Blue" language, apparently) has a single-expression rule for conditionals. All of its conditionals are done using the 'condition ? true : false' operators common to C and Perl, with the false case being purely optional. I'd say braces (or parentheses) are the way to go there, too, unless you're working with a very short single-line statement.
