These are all things one might expect to work in a helper that is capable of handling multiple branches (which our testgit helper in theory should be able to do, as it is backed by git). All of these bugs are specific to the import/export codepaths, so they don't affect helpers like git-remote-curl that use fetch/push commands.

The first and fourth tests are about fetching and pushing new refs, and demonstrate bugs in the git_remote_helpers library (so they would be most likely to impact helpers for other VCSs which import/export git).

The second test is about importing multiple refs; it demonstrates a bug in git-remote-testgit, which is mostly for exercising the test code. Therefore it probably doesn't affect anyone in practice.

The third test demonstrates a bug in git's side of the helper code when the upstream has added refs that we do not have locally. This could impact git users who use remote helpers to access foreign VCSs.

All of those bugs have fixes later in this series.

The fifth test is the most complex, and does not have a fix in this series. It tests pushing a ref via the export mechanism to a new name on the remote side (i.e., "git push $remote old:new").

The problem is that we push all of the work of generating the export stream onto fast-export, but we have no way of communicating to fast-export that this name mapping is happening. So we tell fast-export to generate a stream with the commits for "old", but we can't tell it to label them all as "new".
