There is confusing ULR aliasing going on.

I'm putting remarks into the comment section of

https://eu.swi-prolog.org/pldoc/doc_for?object=digit//1

Instead of any of these:

• Found by going through the "search documentation" box
  • https://eu.swi-prolog.org/pldoc/doc_for?object=integer//1
  • https://eu.swi-prolog.org/pldoc/doc_for?object=digits//1
• Generated by putting an URL like "digit∕∕1" into a comment box
  • https://eu.swi-prolog.org/pldoc/doc_for?object=dcg_basics%3Adigit//1
  • https://eu.swi-prolog.org/pldoc/doc_for?object=dcg_basics%3Adigits//1
