I'm guessing that no-one tried
cat file | grep -e "word1 word2" -e "word1
word2"


its a little tricky to get grep to match newlines but if you type the line
followed by return, if you haven't closed the quotes it is treated as a newline
character.
cat file | grep -e "word1 word2" -e "word1<return>
word2"
