bug#31125: 26; (emacs) `Highlight Interactively'

[Drew Adams]

In the Emacs manual, `i symbol TAB' shows `Highlight Interactively' as a
place where symbols are mentioned.  They are, via
`highlight-symbol-at-point'.  This perhaps the only place in the Emacs
manual where symbols are mentioned.

1. It seems (?), by tracking backward through `highlight-symbol-at-point'
and then (thing-at-point 'symbol), that `highlight-symbol-at-point' is
about highlighting Lisp symbols, not text that has characters with
symbol-constituent syntax.  If so, it would be helpful for the doc of
`highlight-symbol*' to specifically say "Lisp symbol".

2. Assuming that it is in fact about Lisp symbols, please consider
adding a link in (emacs) `Highlight Interactively' to (elisp) `Symbols',
so readers of the Emacs manual can more easily discover something about
Lisp symbols.
