Rather than blindly fixing this, perhaps a bit of thought needs to be
applied to why this code looks like this in the first place.
See commit c6821613e653a (which looks like the bletcherous "do too many
things at once" commit indeed), although the actual diff appears to be a
"no harm, no foul" against this commit, where the issue already existed.

Larry? Can you reach back to 2014 and remember why this code
looked like this in the first place?
