Thanks, now I think I understand the problem. And you're suggesting the 
alternative solution also proposed previously in the 
https://lists.gnu.org/archive/html/emacs-devel/2021-01/msg00156.html 
discussion.

Please go ahead with the patch, though it would be better to use a 
version of it which fixes the same behavior in two other related 
functions as well. The previous patch for that approach is here: 
https://lists.gnu.org/archive/html/emacs-devel/2021-01/txtDduOxGoiGz.txt

(From the message 
https://lists.gnu.org/archive/html/emacs-devel/2021-01/msg00345.html).

Also, since it will fix the double-slash problem, we can undo the change 
from 331e40a8fd491ceb35c08a3345785dab61bc60d9, the one that made our 
comparisons lax (to match both single and double slashes).
