hg clone --update REV doesn't update working dir to REV but head of branch 
'default' instead.

$ hg init r0
$ cd r0
$ echo a >> a
$ hg commit --addremove -m 'add a'
adding a
$ echo a >> a
$ hg commit --addremove -m 'append a'
$ cd ..
$ hg clone --updaterev 0 r0 r1
updating to branch default
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd r1
