Is there a way to get the commit ID of a patch that was cherry picked
(or via a manually applied patch)? I'm trying to get an equivalent to
git branch --contains, but instead of comparing the commit ID, it
compares patch IDs so it works for cherry picks and manual patches. It
seems like git cherry almost does what I want, but it only seems to
show the commit ID of the commit on the other branch rather than the
branch I specify to git cherry. I may just be using git cherry
incorrectly though.

For example, commit 3642151 on branch A was a cherry pick of a commit
460050c on master:

$ git branch -a --contains 3642151
  A

$ git branch -a --contains 460050c
* master

$ git cherry -v master 3642151
- 3642151435ce5737debc1213de46dd556475bfad1 fixed bug

I assume that means an equivalent change to 3642151 is already in
master (which it is, as commit 460050c). But I want to find out the
commit ID on master that's equivalent to 3642151 (i.e. something that
tells me it's 460050c).

I'm basically looking for something like git branch --contains, but
that searches by patch ID so it can find cherry picked or manually
applied patches:

$ git branch -a --contains-equivalent 3642151
* master (via commit 460050c)
  A (via commit 3642151)

Is there a way to do that?
