Note that in the context of path manipulation, if we compare paths at all,
we want to compare paths just as the file system does. So we don't really
want "case-insensitive string comparison" as such. We just want string
comparison that exactly matches the underlying file system.

That having been said, it is probably difficult if not impossible to do this
for the various reasons already cited.
