[exim] Manual, current, Chapter 49 : curly brackets missing …

http://www.exim.org/exim-html-current/doc/html/spec_html/ch-some_common_configuration_settings.html


I would like to ask if there is a set of curly brackets missing on

   ${if match {$return_path}{^(.+?)-request@???\$}\
      {$1-request+$local_part=$domain@???}fail}

should:-

if{ ....{} {} \
{} fail }

be:-

if{ ....{} {} \
{} {fail} }



Thank you.
