Hmph, when I was reading the discussion between you and Peff, I
didn't expect it end up with a change too specific to this single
attribute.  I was instead imagining that a change would come closer
to where we call iconv (perhaps we muck with in/out_encoding
parameters to iconv_open()), so that places other than the
working-tree-encoding (e.g. commit log message encoding) would start
honoring the same configuration variable in a consistent way.
