* bug#44418: 28.0.50; Spliced variable not matched as symbol in isearch

  To: 44418

Severity: minor

0. emacs -Q
1. (let (x) `(,@x))
2. M-s _ x

This highlights the bound x, but not the spliced x.  The same happens
with 'M-s .' or the equivalent 'C-M-s'.

This is because lisp--mode-syntax-table gives 'prefix' syntax to ?, and
'symbol' syntax to ?@.  Is it possible to give 'prefix' syntax to ",@"
as a whole, and in general?

[This behaviour exists since at least as far back as Emacs 24.5.1.
 I wouldn't be surprised if this has been reported before,
 but my searches came up dry.]

Thanks,
