The patch is not as bad as renaming "this" and leaving "that" behind
but in the original, "this" and "this_dir" were treated as a pair.
"this" was a score for a single item in the directory, "this_dir"
was the sum of these scores for entries in the directory.
So renaming "this" to "sum" and leaving "this_dir" as-is looks like
readability regression. Perhaps replace "this_dir" with "sum_changes"
and "this" with "changes" instead, or something like that?
