Looking at the code, it would appear that if there is a core.editor set, it
always overrides any env variable passed. Passing --config to the b4 command
won't do the right thing, because the above would set "b4.core.editor" as the
variable, which is why it's not working.

The right course of action here is to reverse the logic and follow git's
preference:

    GIT_EDITOR -> core.editor -> VISUAL -> EDITOR -> vi

I'll make a bug out of this.
