This is accurate, though I'll add that the development version of
libgit2 now uses SecureTransport instead of OpenSSL on Mac OS X.

But this is just the default. You can replace what libgit2 will use as a
transport if you have special needs. Visual Studio use their own network
code, and the cargo package manager uses libcurl. Eventually libcurl
support will likely be added to mainline libgit2, when we find time.
