• For to have a closer look at this problem I fixed a few hundred links using AWB (mainly page names starting with chars '0..9') and I noticed two things to be observed:

- There are links that contain invisible LTR marks and thus require special treatment.

- The {{Synonym taxon category redirect}} template transcludes {{Category redirect}}. Depending on your implementation (I don't know how you do detect the double catredirects) this might possibly need to be handled specially as there are catredirecting pages having more than one outgoing link pointing to other redirecting pages or to somewhere else: Illustrating this by an example: Category:Anagallis would be a false positive pointing to Category:Lysimachia but having also an outgoing page link to redirecting Category:Anagallis arvensis. But maybe that's irrelevant due to your algorithm.

• Yes i'm aware of it, discussing with zhuyifei1999, thanks for the reminder :) --Gabrielchihonglee (talk) 14:09, 14 January 2018 (UTC)

•  Info: I suppose there are about 8,000 double category redirects to be fixed, some of which are years old. --Achim (talk) 10:23, 13 January 2018 (UTC)

  My test shows that there are around 8762, excluding some rare exceptions like 'Category:User:...' ones which may have errored. --Zhuyifei1999 (talk) 15:03, 14 January 2018 (UTC)

• Forgot to mention: I think it might be a good idea to resolve template redirects like {{Seecat}} → {{Category redirect}} on the fly if a category link is to be fixed anyway. --Achim (talk) 11:01, 13 January 2018 (UTC)

• You can see it changing the template here: https://commons.wikimedia.org/w/index.php?title=Category:Music_for_special_occasions&diff=prev&oldid=279729052 :) --Gabrielchihonglee (talk) 06:46, 15 January 2018 (UTC)

• @Schlurcher: @Achim55: ran test (~45 edits) --Gabrielchihonglee (talk) 00:47, 15 January 2018 (UTC)

Looks good to me. --Schlurcher (talk) 13:55, 16 January 2018 (UTC)

No objections, looks good to me, too. --Achim (talk) 19:52, 16 January 2018 (UTC)
