* lib/mc.sh: create temporary files in ~/.mc/tmp in order to avoid
symlink attacks (mcfn_install and the man page still needs to be
updated).
* src/main.c (print_mc_usage): Print the bug reporting address.
(main): Put prompt in a new line at termination.
* vfs/shared_ftp_fish.c (get_line): Fixed off by one error ('\0' might
have been written one slot past the supplied character array).
* vfs/ftpfs.c (resolve_symlink_without_ls_options): Don't dump core on
strange symlinks (ls -la doesn't reveal where the symlink points to
and ls -lLa doesn't resolve the symlink either)
Added protection against recursive symbolic links.
