csvgrep -r doesn't find matches across newlines

Created by: gabebw

I'm using csvkit 0.9.0.

Given the following CSV in test.csv:

user_id,body
gabebw,"IRC
AIM"

csvgrep can find the row when matching on IRC, which is on the first line:

$ csvgrep -c body -r IRC test.csv
user_id,body
gabebw,"IRC
AIM"

But when I try to match on AIM, which is on a newline but still part of the row, csvgrep does not find the row:

$ csvgrep -c body -r AIM test.csv
user_id,body

Am I using -r incorrectly, or maybe passing it the wrong input?
