Thanks to napgravy for figuring this out. It seems the DOS-style
line-endings that prevented uniq from getting rid of them. This
reduces the ad domains from ~140,000 to around ~120,000 but it is much
more accurate.
In addition to the extra domains, there are numerous performance
improvements so the script runs faster. There were also some
extraneous domains that were either blank or had some special
characters that needed to be removed.
Since the ad lists are not under my control, the end of the script will
now tell you how many domains will be blocked. In case the sources it
pulls from ever update, you can run this script again and see the
difference.
