Bug#942037: perldiag: bad example for "Unescaped left brace in regex is deprecated ..."

[Jakub Wilk]

Package: perl
Version: 5.30.0-6

The perldiag manpage, in the section "Unescaped left brace in regex 
is deprecated ..." reads:

   The contexts where no warnings or errors are raised are:
   [...]
   •   as the first character in a parenthesized grouping like
        /foo({bar)/
        /foo(?:{bar)/

But /foo({bar)/ does trigger the warning:

   $ perl -pe '/foo({bar)/' < /dev/null
   Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.32), passed through in regex; marked by <-- HERE in m/foo({ <-- HERE bar)/ at -e line 1.
