I fixed this by checking whether the first command is NULL; originally
this case was handled by checking whether the command list itself was
NULL. It could also be fixed by having process_file() return NULL in
the case of an command-less file, but it seemed more churn for no actual
reason, since the case is going to be rejected by exiting the program
anyway.
