Yes. Credit goes to Jonathan Tan for this trick.

The eternal struggle of contributing patches that are easy to review. ;)

With the assert we'll have a run time check, which is not desirable
compared to a compile time check. And from a reviewers point of view
running a "rebase -x make" on the series that Junio queued is easier
than to reason about the "assert(r = the_repository)" IMHO.

Glad you're ok with this approach.

Thanks for looking at the refs specific code,
Stefan
