ui: avoid mutable default arguments

I almost introduced a bug around this code by accidentally mutating a default
argument. There's no reason for these to exist.

It is OK to not assign {} to environ in ui.system because util.system knows how
to deal with that.

from mercurial.hg import parseurl

def testparse(url, branch=[]):
    print '%s, branches: %r' % parseurl(url, branch)

testparse('http://example.com/no/anchor')
testparse('http://example.com/an/anchor#foo')
testparse('http://example.com/no/anchor/branches', branch=['foo'])
testparse('http://example.com/an/anchor/branches#bar', branch=['foo'])
testparse('http://example.com/an/anchor/branches-None#foo', branch=None)
testparse('http://example.com/')
testparse('http://example.com')
testparse('http://example.com#foo')
