// 1. colons are replaced by underscores
// 2. there's a leading slash, even for Windows paths: "C:/foo/bar" ->
// "/C_/foo/bar"
// 3. double slashes in UNC prefixes are replaced with a single slash
// We can handle 2 and 3 together by unconditionally adding a leading slash
// before replacing double slashes.
