[MERGE][Bug #56322] bzr init should accept --create-prefix like bzr push does

Hey Aaron,
Thanks for the feedback!  It's reassuring to know I'm not writing
complete rubbish.

Looking at it now, the former two come from missing a line break when
copy-pasting the abstracted code and the latter from mimicking the
--create-prefix test code in test_push.  I still haven't quite got the
hang of which lines get copy-pasted in Vim. :p


Thanks again,
