Hi Arthur, thanks for the fast answer.

I created a PR, please take a look:
https://github.com/scheme-requests-for-implementation/srfi-1/pull/2

It only changes the implementation, and not the html file, since I'm not
sure the html can be changed due to its final status. The text is
actually correct, since lset-adjoin! is mentioned under "Linear
Updates". But it could also be mentioned under "Set operations on lists"
like the others. Not a big deal though.

Best regards,

Ricardo
