Re: [RFC/PATCH jn/merge-renormalize] merge-recursive: expose merge options for builtin merge

There are two very similar blocks of code that recognize options for

No functional change intended.

It makes sense, but I wonder why you chose to do "if (fun() <= 0) error"
instead of usual "if (fun() < 0) error"...
