Which is correct, since 508b0c1b22 was cherry-picked from master.

The commits _are_ present, according to Git, but the corresponding
changes to the worktree aren't.  Is that what you mean above?

Again, what do you mean by "check out 508b0c1b22" (how to check and on
which branch), and what do you mean by "changes indeed exist there"?
Given the above ambiguity and the fact that we have two branches,
please be very specific when you say such thing, to avoid any
misunderstandings and confusion.  This issue is confusing enough
already.

So you are saying that this problem is due to a bug in gitmerge.el?
If not, what do you mean by "by mistake"?  I didn't merge any commits
manually, I invoked "M-x gitmerge", and it didn't report any problems
except with merging emacs-29/NEWS master/NEWS.29.  So who made the
mistakes you suspect here?

You are saying that all of the above commits don't have their changes
in master?  How did you generate the above list?

Thanks.
