Re: [PATCH 04/19] teach remote-testgit to import non-HEAD refs

Sverre Rabbelier [off-list ref] writes:

From: Jeff King <redacted>

Upon receiving an "import" command, the testgit remote
helper would ignore the ref asked for by git and generate a
fast-export stream based on HEAD. Instead, we should
actually give git the ref it asked for.

This requires adding a new parameter to the export_repo
method in the remote-helpers python library, which may be
used by code outside of git.git. We use a default parameter
so that callers without the new parameter will get the same
behavior as before.

  Unchanged from Peff's series.

This seems to be slightly different from what was sent to the list,
though.  Using refs=None as default and assigning ["HEAD"] is more in line
with the standard Python practice, so the implementation is better.

But "do we still append HEAD after --import-marks?" still stands.
