config: un-break showconfig wrapper when environment variables are used

This was broken when hg was picking up $EDITOR etc and showing that in
the showconfig --debug output. No test because I can't figure out how
to thread the environment variable down into the executed hg binary,
but this fixes the failure on my laptop.
