That is because some functions have more than one example per group (for
example, string-lessp is documented in the "comparison" and "string"
groups), but the "s" is added when a function is documented in _more
than one group_.

I think a more accurate logic to add the "s" is to count the number of
"arrow characters" that separate the form from the example.

Could you give a try to the attached patch, and install it for me if all
works correctly?  Thanks.
