Fix a subtle bug when running interal poems

This patch fixes a bug for internal poems, where the output would always
get split on newlines, regardless of the verse's verb. This breaks
things like 'export DIR=`ls`', since output from `ls` might have
newlines, meaning that $DIR will only contains the first item from the
`ls` command. This will only perform the newline split when sending the
output to a non-builtin command.
