Hmm, interesting. I, too, see this happening on a fully updated rawhide machine using NetworkManager:
$ uname -a
Linux ktmtoshiba 3.13.0-0.rc0.git7.1.fc21.x86_64 #1 SMP Tue Nov 19 02:18:43 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.238.116 netmask 255.255.255.0 broadcast 0.0.0.0
inet6 fe80::ca0a:a9ff:feb1:46c2 prefixlen 64 scopeid 0x20<link>

It would appear to be in the interaction between dhclient and NetworkManager (which actually starts the nic and configures it,
dhclient or NetworkManager?) as my dhclient leases file also shows a broadcast address but, as you can see, none appears on my nic.
Seems like a bz should be raised for this.
