    Yes, it's just a formatting change to make it clear that the break in the 
string means that it's still part of the description.

>             Project: Apache NiFi
>          Issue Type: Bug
>    Affects Versions: 1.0.0
>            Reporter: Keren Tseytlin
>            Assignee: James Wing
>            Priority: Minor
>             Fix For: 1.1.0

> As a user of Nifi, when I want to enable cross account fetching of S3 objects 
> I need the proxy variables to be set in order to generate temporary AWS 
> tokens for STS:AssumeRole.
> Within some enterprise environments, it is necessary to set the proxy 
> variables prior to running AssumeRole methods. Without this being set, the 
> machine in VPC A times out on generating temporary keys and is unable to 
> assume a role as a machine in VPC B. 
> This ticket arose from this conversation: 
> http://apache-nifi-developer-list.39713.n7.nabble.com/Nifi-Cross-Account-Download-With-A-Profile-Flag-td13232.html#a13252
> Goal: There are files stored in an S3 bucket in VPC B. My Nifi machines are 
> in VPC A. I want Nifi to be able to get those files from VPC B. VPC A and VPC 
> B need to be communicating in the FetchS3Object component.
