Heads up: skipping a couple commits when merging emacs-29 to master

[Jim Porter]

In bug#62556, I merged some separate patches for emacs-29 and master. On 
the emacs-29 branch, there were a few test failures that were fixed in 
followups by both Eli and me, but I don't think the commits were marked 
as "Do not merge to master".

Since emacs-29 and master handle these tests in different ways, merging 
those followups will probably fail, so (I think) they should be skipped. 
The commits SHAs to skip are:

  21a4ee209c19031e29e98e4308aa9d67890a0515
  46209b2453b1a53fcf0019f6e1a21b7fef85bcbc
  89e337c3fc9a51454afb86176a507f46c198be9f

Thanks, and sorry for any difficulties with merging.
