work fine

Currently go-git doesn't support short hashes.

why don't we just change the error message? to something like:
short sha1 reference is not supported, please use the full 40 characters

[smacker]

because it's convenient to support short sha1s.

git log --oneline
/find commit from which we want to test
<copy-past to --from and run>
base revision '9c3b4a2' error: reference not found

[carlosms]

I think we all agree it's convenient and it would be nice to support it if possible.

But given that this depends on support from go-git, and it's been stuck for months, I propose to change the error message to clarify that you need to use the full sha1.
Then my question is if that's good enough to close this issue, or if that's a temporary workaround and we should keep this issue open.

It makes sense to improve error message disregard of this issue
