In the following version of the Hindi Wikipedia article on
महाकश्यप :
http://hi.wikipedia.org/w/index.php?title=%E0%A4%AE%E0%A4%B9%E0%A4%BE%E0%A4%95%E0%A4%B6%E0%A5%8D%E0%A4%AF%E0%A4%AA&oldid=263801

(1) The following category has been entered by the editor:
{{श्रेणी:बौद्ध धर्म}}
But it is being wrongly displayed as: श्रेणी: धर्म
together with this message automatically added from nowhere: ये
श्रेणी बौद्ध धर्म के लिये है ।

That's because the category is getting transcluded (using curly brackets: {{...}}) instead of being added (using square brackets: [[...]]). I fixed this here: http://hi.wikipedia.org/w/index.php?title=%E0%A4%AE%E0%A4%B9%E0%A4%BE%E0%A4%95%E0%A4%B6%E0%A5%8D%E0%A4%AF%E0%A4%AA&diff=264371&oldid=264336

(2) There is just one interlanguage link added by the editor:
[[en:mahakashyapa]]
But the page displays a few dozen automatically produced wrong interlanguage
links.

This was also due to the transclusion, as the category's IW links were added to the page. Note that a bot has since added some more, so there's now 8. Since this wasn't a bug in MW, I'm closing as WORKSFORME.
