Modified: branches/batctl-0.2.x/bat-hosts.c Log: batctl: avoid parsing bat-hosts multiple times
Currently, running batctl from the home directory leads to warnings ("Warning - mac already known") if ~/bat-hosts exists. This is caused by batctl parsing both "~/bat-hosts" and "bat-hosts" which happen to be the same file when the working directory is ~
This patch adds duplicate file name detection to bat_hosts_init() to avoid these warnings.
