[QUESTION] how to diff one blob with nothing

Hi,

I want to diff two blobs right now, and one of them may be empty, so I tried using 0000000000000000000000000000000000000000 or e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 (empty blobID) to test its effect, and the result I found was:

git diff 00750edc07d6415dcc07ae0351e9397b0222b7ba 0000000000000000000000000000000000000000 fatal: bad object 0000000000000000000000000000000000000000

git diff 00750edc07d6415dcc07ae0351e9397b0222b7ba e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 fatal: bad object e69de29bb2d1d6434b8b29ae775ad8c2e48c5391

Since the "empty object" has not been created, the git diff operation fails.

There may be some other methods [1] available to diff two blobs by creating an empty blob, but I don't want to create this empty blob, are there any other ways to solve this problem?
