I still wasn't happy with this, so I'm again tweaking it a bit more.
Since you don't need to indent content to stay in a fence, some people
won't. Consider, for example, somebody just pasting some code in from
somewhere else, and not reindenting it because Ducktype allows that.

    [code]
    [[[
def frobnicate():
    pass
    ]]]

With my change away from using the indent of the first line, every line
here will have at most four spaces stripped, which is clearly wrong. At
the same time, I want to keep the ability to indent the first line, as
in the prior example.

So, the solution is this: the indentation trim will be the minimum of
the indent of the first line and the indent of the [[[ marker. I think
this behavior will most closely match what most people will expect.
