Starting from "emacs -Q -f eshell":

   ~ $ (setq eshell-glob-splice-results t)
   t
   ~ $ echo /ssh:localhost:~/file.txt
   /ssh:localhost:~/file.txt
   ~ $ echo /ssh:localhost:~/file.txt
   Wrong type argument: listp, "/ssh:localhost:~/file.txt"

The third command should have the same result as the second (the second 
works because Tramp isn't loaded yet at the time).

This is a bug in a new Eshell feature in Emacs 30 and thankfully has an 
easy fix (see attached). Eli, is this ok for the release branch? I added 
a regression test for this too.
