It might be simpler to default commit_option= empty like the others, and

that the shell ignores it when it's empty.

"--no-no-commit" should just be "--commit" instead.
The real flag is called "--commit" (git help merge), so subtree
should follow suite by supporting "--commit" and "--no-commit" only.
