I've done a quick style review, but have not looked closely at the

another review (possibly by me, if I have a longer chunk of time to
spend on it) before you get an ack.

Use gnulib's intprops.h for INT_BUFSIZE_BOUND(ifindex) instead of
hard-coding an array of 20 bytes.  At which point you could safely use
sprintf instead of snprintf, for a micro-optimization (although I'm
still fine seeing snprintf).

Explicit initialization to false is not necessary; the language
guarantees 0-initialization of variables at file scope.

As long as you are making a cosmetic-only change here, does it make
sense to switch to 'unsigned int i' for the iterator?

I didn't notice anything else in my rapid style read-through.
