nit: whitespace clean

[schwehr]

This one is not super important, but it would be nice if the code formatting could be standardized. My ideal would be to pick a clang-format setup and enforce it. But baring that, it would be helpful if the code was at least trailing whitespace clean. e.g.

find . -type f | xargs perl -pi -e 's/\s+\n/\n/g'

You're right: it's a nit.

I did it anyway.

Are you aware that JPL -- the institution responsible for deep space missions like Voyager, Mars Pathfinder, Opportunity, Curiosity, Cassini, Juno, etc. -- doesn't enforce any formatting standard for C code?

I worked on Pathfinder, Opportunity, Curiosity, Phoenix, and Polar Lander. I recommend not following them as examples of what to do for robust software engineering :(
