I'm sorry, but I don't understand the point of this discussion
anymore. There is already a solution for this problem: it's the fix
for issue #3865. This implements the following for the command line
client:

   If there is no case-exact match on disk, but there is a case-exact match
   in wc.db, assume the user refers to the latter. Otherwise case-normalize
   like any other Windows app.

IMHO this is the most natural and simple way to do this. I don't see
the need for more complicated schemes.
