This explains why, but the code isn't clear as to what's happening or why this fixes the infinite loop. For example, a far superior comment might be:
# If we don't check for an empty prefix after the split (in other words, archive = / before and after the split), we _can_ end up in an infinite loop on a rare corner case affecting a small number of users
This comment explains the conditions, why we care (it affects users), and the risk to making a change (if we break this again, we may not find out about it quickly)
