This makes empty bodies truly empty, and fills in the
default UTF-8 encoding for an empty encoding.

I think this covers everything that might happen in common practice.

I do not think the latter is correct.  Replacing with an empty
string might make sense, although I haven't thought through the
issues.

Fair enough. I originally put in an empty string, but tried to be (too)
clever with UTF-8 (I was under the impression that commits without
headers were assumed to be in UTF-8, unless there is some legacy
override set). I'm fine with whatever makes sense, but I think printing
<unknown> is silly: we _do_ know.
