Re: [PATCH 05/11] completion: add test showing subpar completion for git switch --orphan

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The proposed SQUASH you have in gitster/jk/complete-git-switch is
correct. The commit message body is correct, but the title could be
reworded to

"completion: stop completing refs for git switch --orphan"

I can send a v2 if that would be helpful, and I've got it fixed up
locally if other review increases the need for a new spin.

Thanks,
Jake
