-Convert a MSYS path list to absolute, Windows-native format.
+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.
+3. Translate each path to Windows-native format.
-Paths starting with '%emacs_dir%' will be passed verbatim to the
-standard output.
+Relative paths or 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
+Each non existing absolute path will be translated by looking for its
+deepest existing directory, which will be translated and the remainder
appended.
