rtlsdr git adresse don't semm to work

[PhSur]

Hello

I've tested the rtlsdr brew install, but the git url don't respond.
I propose to update the formula "rtlsdr.rb"
Just change
head 'git://git.osmocom.org/rtl-sdr.git'
by
head 'http://git.osmocom.org/rtl-sdr', :using => :git

I've tested them behind a firewall or not, it works well too.
