The use case was that server with repo wasn't responding for a while and I was thinking how to solve that. Thanks for the answer!

The main issue is applying the patch requires git clone and that would fail on local (not pushed) commits.
What's the use case itself ?
(btw, if you copy the uncommitted changed into a file and git apply it, it will work)

Hi RoundMosquito25
What do you mean by "local commits" ?

Commits, that are not pushed to the repo
