bug#31623: 27.0; Elisp manual, index entry "; in comment"

[Drew Adams]

>From the text of index entry "; in comment" I would expect a node that
talks about the use of `;' inside a comment.  I cannot imagine what
other sense someone might make of this index-entry text.

But the target of the index entry, node `Comments', does not seem to
say anything about a `;' character inside a comment.

Please consider fixing this somehow - not sure what was intended.
Perhaps the entry text needs to be changed.  Or perhaps it the entry is
not pointing at the correct node.  Or perhaps the node text needs to be
changed, to address whatever the entry is supposed to suggest.
