Grep for Unstructured Multiline Paragraphs

A multiline paragraph is a string in which there are no 'empty lines' - two newlines separated only by whitespace. For example given data.txt:

This is
one multiline
paragraph.

This is
another
multiline
paragraph.

This one is too!

grump takes a file and a list of strings and outputs all multiline paragraphs of this file containing each string in the list. For example:

$ grump -f data.txt this one
This is
one multiline
paragraph.

This one is too!
