I am opposed to this change.

For one, libgit.a is *not* a library with an API, for a good reason:
nothing in Git's development guarantees any kind of stable API. For that
reason, libgit.a is not installed, either, and neither are any headers.

And even more importantly: *iff* you *insist* on using libgit.a in your
project *despite* having been told not to, it is your responsibility to
stay up-to-date with the requirements of it.

One such requirement is that you now implement cmd_main() instead of
main().

So if you want to continue to have an out-of-tree project that links
against the (private) libgit.a, it is your out-of-tree project that needs
changing, not libgit.a.

Ciao,
Johannes
