I wonder if gpg-interface functions can and should be taught to
initialize themselves lazily without relying on the usual
git_config(git_gpg_config) sequence.  I.e. the first call to
sign_buffer(), check_signature(), get_signing_key_id(), etc.
would internally make a git_config(git_gpg_config) call, with the
current callers of git_config(git_gpg_config) removed.
