Description

One way or the other, we should try to sanitize local filesystem paths on Windows, by converting backslashes into regular slahes.

One place to do it is FileSystemFromUri. One complication is that -separated paths can fail parsing as a URI, but we only want to sanitize a path if we detected it's a local path (by parsing the URI). Perhaps trying on error would work.
