So ?? I find it actually quite good practice. Reduces the risk of adding a line later and not understanding why it is always executed.
Absolutely agree...always use the statement block braces. On the Arduinos, since Serial.print() is the most used debugging tool, you probably will eventually need to "brace-out" the if anyway. As sterretje points out, not always using them is a BYITBL waiting to happen (i.e., Bite You In The Butt Later).
