bittornado is too picky about filenames within a torrent.
Even harmless names, such as '...And justice for all' or '.directory'
are considered 'unsafe', and bittornado stops.
Here is a patch to fix this.
New regexp catches all tries to go upwards the directory tree I could
imagine (~user, ../../, /etc/, etc.). Anything else is OK.
Of course, one can download new .bashrc in his homedir.
He could do this with wget as well.
I sent it to upstream author a couple of years ago, but never
got any reply.
