win32: tests around handling forbidden paths Introduce a repository that contains some paths that were illegal on PC-DOS circa 1981 (like `aux`, `con`, `com1`) and that in a bizarre fit of retrocomputing, remain illegal on some "modern" computers, despite being "new technology". Introduce some aspirational tests that suggest that we should be able to cope with trees and indexes that contain paths that would be illegal on the filesystem, so that we can at least diff them. Further ensure that checkout will not write a repository with forbidden paths.
