Does this mean there are two conversions going on, one inside git log
and another inside Tcl?  Is there a reason why it's better to do two
conversions than one, or is it just more convenient that way?

Would an alternative approach have been to read the output of git
cat-file with -translation binary, look for an encoding header, and do
an encoding convertfrom based on the encoding header?  What would be
the disadvantage of such an approach?
