No. Because I know there are patterns which won't exist:

/option: ...

is guaranteed not to exist: '/' can't be part of a file name.

Subversion doesn't have knowledge of the client side file system and
as far as I can see, neither will it be able to grow any. So, since we
can't be consistent with the host platform, we'll have to be
consistent with ourselves (which is case-sensitive).
