Author: Florian Weimer <fweimer@redhat.com>

    conform/conformtest.pl: Escape literal braces in regular expressions
    
    This suppresses Perl warnings like these:
    
    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/^element
    *({ <-- HERE ([^}]*)}|([^{ ]*)) *({([^}]*)}|([^{ ]*)) *([A-Za-z0-9_]*)
    *(.*)/ at conformtest.pl line 370.
