// Returns the directory component of a path, without the trailing
// path separator, or an empty string on error. The function does not
// check for the existence of the path, so if it is passed a directory
// without the trailing \, it will interpret the last component of the
// path as a file and chomp it. This does not support relative paths.
// Examples:
// path == "C:\pics\jojo.jpg",     returns "C:\pics"
// path == "C:\Windows\system32\", returns "C:\Windows\system32"
// path == "C:\Windows\system32",  returns "C:\Windows"
// Deprecated. Use FilePath's DirName() instead.
