As Matthias Kestenholz noted, the flag does not quite mean
"needs prefix" -- it is more like "run setup_git_directory()
before running this command", so rename it to avoid future
confusion.

While we are at it, rewrite the definition of options to make it
obvious that we are talking about flag bits by using standard (1<<n)
notation.
