Long story.  For typical escaping/quoting this does hold.
Of course, for more general rewrites, it doesn't.

Can you give me your file-name-handler code so I can play with it (I
don't have Cygwin at hand, but I should be able to make up the
difference).
I think the problem is in completion--sifn-requote, which is definitely
not prepared for the kind of rewrites you're doing.
