No, it doesn't.
Is there an easy way to implement it to ignore them; I can live with it if not, but a fix would be useful
Probably not. We do love patches though, see Manual:Pywikibot/Gerrit for instructions on how to get started, or ask in #pywikipediabot :)
I have asked in the IRC channel, and it needs a complete rewrite to do this. I don't have the time ATM, so will need someone else to do this; Feel free to mark as resolved.
