The security team's Coverity instance has started to show this
complaint now too. So I'm going to go ahead and push this change
in HEAD. It's probably unwise to change it in stable branches,
since there's at least a small chance some external code is using
COMMAND_TAG_NEXTTAG for the same purpose tag_behavior[] does.
But we aren't anywhere near declaring v17's API stable, so
I'd rather fix the issue than dismiss it in HEAD.
