I first wrote out the ${sg} part:
${sg{}{}{}}
I then added some newlines for readability:
${sg{
}{
}{
}}
I then added the arguments which we want to pass to ${sg}:
${sg{
${readfile{/etc/exim/dkim/test2.cadera.com.pl.selector}}
}{
\n|\
}{
}}
I then compressed it down to a single line:
${sg{${readfile{/etc/exim/dkim/test2.cadera.com.pl.selector}}}{\n|\ }{}}
It's almost the same as your second version apart from a semi-colon
being out of place.
