But "git merge-index git-merge-one-file" called in the context of scrpted Porcelain has the directory that has *OUR* git-merge-one-file as the first element on $PATH, I think, so it may be perfectly safe to use the "ah, the command name we are asked to run happens to be git-merge-one-file, so let's use the internal version instead without spawning" short-cut.
