Adding tty makes sure docker attach won't be accidentally detached
by ctrl-C (there are better ways of doing this but this one works
for now)

shell-words more closely emulates Bash's tokenizer rules (but without
doing things like environment variable expansion) which allows us to use
multiline strings as reasons, etc.  Unfortunately entering newlines
still won't work the way we've written things since shell-words does not
right now give enough information to incrementally build up a valid
string, just says there was a tokenizing error; but maybe in the future
we can fix that.
