scripts/git: Quote shell arguments where possible

Most shell arguments should be quoted to avoid mistakes.

But since all branch names are hard-coded, or supplied by the script user,
we don't need to be too concerned about command injection.

Quoting all shell arguments would take a major refactor.
(Probably using arrays.)
