Would anyone object to \df displaying a function's volatility? Maybe
limit it to \df+?
Ideally we would have a short header for the column so that it doesn't
take too much space, and specify the setting with a single letter. The
meaning of each letter we could display at the bottom of the table as a
footer (something we were going to do for \z too I think?)
Thoughts?
