I played with this years ago, but readline does not really offer a
good way to easily get what we want (the whole statement, chunked into
nice bits to analyze). Of course at this point we should think about
making things more generic so we can drop in whatever readline-alternative
comes along in the future.

Insane amount of work? Check. Inredibly stupid? No, I think we've done
pretty good given the limitations we have. You want to see incredibly
stupid, see some of the *other* CLIs out there (hi, mysql! :)
