I have reduced the patch removing any Win32 parts.

+ path: Use UTF8 iteration for HFS chars

+
+ checkout: disallow bad paths on HFS
+
+ HFS filesystems ignore some characters like U+200C. When these
+ characters are included in a path, they will be ignored for the
+ purposes of comparison with other paths. Thus, if you have a ".git"
+ folder, a folder of ".git<U+200C>" will also match. Protect our
+ ".git" folder by ensuring that ".git<U+200C>" and friends do not match it.

+
+ checkout: disallow bad paths on win32
+
+ Disallow:
+ 1. paths with trailing dot
+ 2. paths with trailing space
+ 3. paths with trailing colon
+ 4. paths that are 8.3 short names of .git folders ("GIT~1")
+ 5. paths that are reserved path names (COM1, LPT1, etc).
+ 6. paths with reserved DOS characters (colons, asterisks, etc)
+
+ These paths would (without \\?\ syntax) be elided to other paths - for
+ example, ".git." would be written as ".git". As a result, writing these
+ paths literally (using \\?\ syntax) makes them hard to operate with from
+ the shell, Windows Explorer or other tools. Disallow these.

+
+ win32: use NT-prefixed "\\?\" paths
+
+ When turning UTF-8 paths into UCS-2 paths for Windows, always use
+ the \\?\-prefixed paths. Because this bypasses the system's
+ path canonicalization, handle the canonicalization functions ourselves.
+
+ We must:
+ 1. always use a backslash as a directory separator
+ 2. only use a single backslash between directories
+ 3. not rely on the system to translate "." and ".." in paths
+ 4. remove trailing backslashes, except at the drive root (C:\)
