clobber case_sensitive (it's pretty hard for it to provide case-
sensitive semantics), but case preservation is probably orthogonal to
Now that it's possible to look at filesystem capabilities, it's
probably also possible to move the case normalisation behaviour into a
I won't have email for the next couple of weeks, but I'll look more
