Probably a ${sg } (assuming you don't have to handle *escaped*
newlines)
${sg} was also my first initial reaction, but then I thought, maybe
${extract} with newline as separator is less painful?
works for the first line:
> ${extract{1}{\n}{${readfile{/etc/group}}}}
wheel:*:0:root,km
works for the 10000th line:
> ${extract{10000}{\n}{${readfile{/var/log/exim/mainlog}}}}

works for 10000th line with ${run}, too:

have to look at that permission error there, I guess :)
