Dope, thank you very much! Upon further review of the query, I think we can save a few lines and hopefully some ms by replacing

The query looks good! Thank you! What do you think about adding it to Template:Property documentation?

Do You achieved optimizations for the query?
I tried to adopt the query for archINFORM data related entries and always get timeout errors...

I was made aware of this ticket at the last office hour per @Epidosis comment.

I can confirm the problem reported by Seudo; more importantly, it does happen even with two pages: assuming only Foo.djvu/11 and Foo.djvu/12 appear in the watchlist as recenlty modified, and Foo.djvu/11 is visited, Foo.djvu/12 will also be marked as visited.

The problem is also present when trying to use substitution to quickly change the capitalization of the text, i.e. {{subst:uc:text}} and {{subst:lc:TEXT}} fail to work. As far as I have tested this seems to be limited to the Page: namespace on the French Wikisource, with Talk pages being unaffected.
