Yep, I found these changes via a similar-looking Python script. I like
the Perl version, though, since it gives a path for inclusion so that we
can automate this task.

should be sorted. Perhaps if we include this in the static-analysis
script, we could define a whitelist of lists that we want to keep
sorted?
