bug#55149: 29.0.50; Commit f30625943e broke magit/with-editor

[Tassilo Horn]

I think he means what I've written in my original report.

```
With stock-emacs when doing "emacsclient foo.txt", it just prints
"Waiting for Emacs..." but finishes immediately.  The existing emacs
doesn't have a foo.txt buffer thereafter.  "emacsclient -c foo.txt"
results in a new frame which has a foo.txt buffer but it is not
displayed in a window...
```

Testing this strange emacsclient behavior requires no external packages at all.
