+From a826b19625caebed6dd0f3fbd9d0111f6c83737c Mon Sep 17 00:00:00 2001

+Subject: [PATCH] path/filepath: do not Clean("a/../c:/b") into c:\b on Windows
+
+Do not permit Clean to convert a relative path into one starting
+with a drive reference. This change causes Clean to insert a .
+path element at the start of a path when the original path does not
+start with a volume name, and the first path element would contain
+a colon.
+
+This may introduce a spurious but harmless . path element under
+some circumstances. For example, Clean("a/../b:/../c") becomes `.\c`.
+
+This reverts CL 401595, since the change here supersedes the one
+in that CL.
+
+Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this issue.
