NAK:
* [minor] broken whitespace
* [minor] adding braces to singleton C statements
* [major] makes a simple loop much more annoying to read
There is no critical hard deadline for this loop, as with most error

Since error handling code is exercised much less frequently than regular
code, I would rather KISS.
