py3: use bytes stdout in hghave.py
This fixes a failure in test-run-tests.t around notarealhghavefeature. It seems
crazy to me that all of this needs to be adjusted in all of these tests, but the
line as run-tests.py sees it in _processoutput() before doing anything is
already mangled with a trailing '\r'. Switching to normalizenewlines=True for
TTest works, but I'm sure that breaks other stuff.
$ hg init a
$ cd a
$ hg init b
$ echo x > b/x
Should print nothing:
$ hg add b
$ hg st
$ echo y > b/y
$ hg st
Should fail:
$ hg st b/x
abort: path 'b/x' is inside nested repo 'b'
[255]
$ hg add b/x
abort: path 'b/x' is inside nested repo 'b'
[255]
Should fail:
$ hg add b b/x
abort: path 'b/x' is inside nested repo 'b'
[255]
$ hg st
Should arguably print nothing:
$ hg st b
$ echo a > a
$ hg ci -Ama a
Should fail:
$ hg mv a b
abort: path 'b/a' is inside nested repo 'b'

$ hg st
$ cd ..
