Actually, file-truename works for the cases we've discussed so far:

(file-truename "c:/Projects/emacs/master/lisp/elide-head.el")
"c:/Projects/emacs/master/lisp/elide-head.el"

(file-truename "c:\\Projects\\emacs\\master\\lisp\\elide-head.el")
"c:/Projects/emacs/master/lisp/elide-head.el"

(file-truename "c:\\projects\\emacs\\master\\lisp\\elide-head.el")
"c:/Projects/emacs/master/lisp/elide-head.el"

I did not try a non-ASCII file name; I'm not sure how to construct one
that has a non-ASCII casing issue.

What test did you run that failed?
