If this is the problem, then let's solve it without affecting
make-symbolic-link. The problem you show is in file-symlink-p and/or
in rename-file. Let's solve it there, and let's solve it without
affecting the interactive callers of those functions.

But AFAIU, file-symlink-p can return a quoted name if its argument is
quoted. Doesn't this allow to solve the problem?
