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.

class test_heads(common.basetest):
    def test_empty(self):
        self.assertEquals(self.client.heads(), [])

    def test_basic(self):
        self.append('a', 'a')
        rev, node0 = self.client.commit(b('first'), addremove=True)
        self.assertEquals(self.client.heads(), [self.client.tip()])

        self.client.branch(b('foo'))
        self.append('a', 'a')
        rev, node1 = self.client.commit(b('second'))

        self.assertEquals(self.client.heads(node0, topological=True), [])
