+Convert a MSYS path list to Windows-native format.
 
 PATHLIST should be a colon-separated list of MSYS paths, which will be
 written to the standard output after performing these transformations:
 
 1. Discard empty paths.
 2. Replace: '\' with '/', '//' with '/' and ':' with ';'.
-3. Translate each path to absolute, Windows-native format.
-
-Paths starting with '%emacs_dir%' will be passed verbatim to the
-standard output.
-
-Each non existing path will be translated by looking for its deepest
-existing directory, which will be translated and the remainder
-appended.
+3. Translate absolute paths to Windows-native format.
