Re: newb: Given a commit id, find which branches have it as an ancestor

Johannes Sixt [off-list ref] writes:

Your best bet is perhaps that you create a branch at the commit

  $ git branch tmp-branch your_sha1

so that the commits are not lost, then you cherry-pick them to master.

It could be that there are more commits that are built on top of the one
you are aware of.  Finding unreachable commits from "git fsck --full"
might help you find them.
