Restart bash if there are any errors

How is this for a workaround?
I'd rather not do this, because I have a better fix already in pexpect: set the pager to cat, so `man` doesn't lock things up. https://github.com/pexpect/pexpect/pull/76

Also, passing silently is not the right thing to do here, because that means you're not at a prompt ready to receive input, so the next iteration won't work.
