This ended up motivating a good deal of other infra improvements in order to get Windows right: - `OsString` to complement `std::filesystem::path` - env var code for working with the underlying `OsString`s - Rename `PATHNG_LITERAL` to `OS_STR` - `NativePathTrait` renamed to `OsPathTrait`, given a character template parameter until #9205 is complete. Split `tests.cc` matching split of `util.{cc,hh}` last year. Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>
