commit 3317b1e28607a4e2ca80d9ef340e1461567e1072
Author: Adrian Schmutzler <freifunk(a)adrianschmutzler.de>

alfred-devel: Support interface IDs with more than two digits
Occationally /proc/net/if_inet6 contains interface IDs with
three digits. In this case, the regex in wait_for_ll_address()
does not work anymore and alfred is not starting.
This patch changes the evaluation so that fields are used instead
of the mere position by counting characters.
