Please add a test for GzipFile with a file opened with mode 'wb+'.

This is not what I meant.

Open a file in the "wb+" mode and pass it to GzipFile instead of a filename. Check that that GzipFile is writable and not readable. You can also do the same for "rb+" and other modes. Most likely there are already such tests for "rb" and "wb" (and maybe for "ab" and "xb"?).

Do you want that in this PR, or another one?

Yes, please add tests for all other modes with "+".

Since it emits FutureWarning, the more correct place for these tests is test_fileobj_mode.
