Now c:\bin\ gets transformed into c:/usr/bin/ at the completion prompt, which is
no good: besides being the wrong completion (with respect to c:\bin\, since
there is no c:\usr at the Windows level), the lack of backslashes in the
substituted path completely disables the file-name-handler I'm trying to use.

I feel like I need a hook outside the quoting done by the function with
completion-table-with-quoting. I'll see whether I can mock something up with advice.
