Re: [PATCH v3] checkout: optimize "git checkout -b <new_branch>"

- Ben's patch only affects the "checkout -b $NEWBRANCH" case.  He
checks for it by looking for any other flag that would be a different

and an ongoing maintenance burden because if anyone ever adds any
extra options, this optimization might suddenly break things if that
giant list of checks isn't updated.

Correct.  

Having said that, I do not mind leaving it in 'pu' for the rest of
the cycle, possibly merging it to 'next' after that and keeping it
there, to see how horrible a maintenance burden it would become in
real life, though.
