I think that is what was meant.  Just like "-" abbreviation is handy
for users of "checkout" and "merge", "cherry-pick" might.  I am not
sure if you would often cherry-pick from the previous branch, but
for the sake of completeness and uniformity, the guiding principle
could be "at any point on the command line where a branch name is
accepted, if a '-' could not possibly mean any other thing is wanted
(e.g. doing something on the standard input), it should stand as the
name of the previous branch".

I agree with everything you said in your review.  The patch is going
in the right direction, but it needs a bit more work.

Thanks.
