FWIW, it's HEAD and 6.1. We've actually got the aliases syntax labled
as deprecated in the manpage. We might want to add a feature to set the
broadcast address.

Unfortuanly grep in in /usr/bin so can't be used. You could do it
with sh variable mangling and case though. Something like:
{ while read _var; do
_var=${_var%%=*}
case $_var in
ifconfig_${IFACE}_alias*)
<...>
;;
esac
done } < `set`
