Security issue with Hobbit "config" command. 🔗 link

The config directive does not stay locked into the etc directory but

Thanks, this was not meant to happen. There was actually a security
check in the code, but it got two parameters in the wrong order, so
it would always grant access. A patch is attached.

Hi Henrik

maybe a patch should be released for 4.1.2p1 (I've tested, any file can 
be read) ?
