Seem to be missing some subjects in that sentence. ;-) Perhaps: Move the default warning to the point where we can check if we can fast-forward or not.
No functional changes.
You didn't explain the reasoning for the change here, though I suspect it makes it easier to change the default to ff-only later. However, looking over the patch and pulling up the code, I actually find it pretty odd that this warning was in a function named config_get_rebase(). The warning is not rebase-specific, and so clearly does not belong there. And for such a function name, the only kinds of warnings I'd expect are ones where the user configured some option but set it to a value that cannot make sense. So it all around seems like the wrong place to me, and I find your patch to be a good cleanup. It would benefit from a slightly improved commit message though. :-)
