Again, no proper review from me, but I've tried the patches.

Completion looks good, just like with the previous one.

But here's an error I encountered when trying to call a command with 
asterisks without expanding them with completion:

$ ls ~/Documents/Sp*
Wrong type argument: stringp, ("~/Documents/Spain/")

This issue is present in master (without the patches applied), but not 
in emacs-29.

The patch(es) fix a similar error in company-mode completion -- 
hopefully the straight evaluation could be fixed as easily.
