fix for redirect splitting.

Hey,

i think there is a bug in the two lines below. I don"t see why there should be a '-1'. 
Here is some debug output of me running hydra against my redmine installation, using my working credentials, which results in a redirect that should be followed ([MOFOE] added by me). 

Old code:

You can see that it removes the last character from the redirect location resulting in a HTTP 404.

Here is how it looks after removing the '-1':

[DEBUG] hydra_receive_line: waittime: 32, conwait: 0, socket: 5, pid: 27649

Now it works as expected. 
I hope i didn't overlook something.
