I noticed this issue when resolving conflicts with our VFS for Git-enabled
branch in microsoft/git.

When I moved the global for core.sparseCheckout along with creating the
global for core.sparseCheckoutCone, I dropped the "extern" by habit. (We are
dropping these from function declarations, usually.) However, this means
something different for variables, and could lead to bugs. I haven't found
any, but it's better to be safe, right?

Thanks, -Stolee
