It wasn't forgotten, but thanks anyway.

I have a few minor comments to this version:

Please reformat/refill this so that "(MANUALs . URL-SPEC)" is not
broken between two lines.

                                 ^^^^^^^^^^^^^
This triggers a byte-compiler warning:

  In Info-url-for-node:
  info.el:1868:32: Warning: `seq-contains' is an obsolete function (as of 
27.1); use `seq-contains-p' instead.

> +    (error "No URL-specification associated with manual-name `%s'")))

And this line triggers the following byte-compiler warning:

  info.el:1896:6: Warning: `error' called with 0 args to fill 1 format field(s)
