- Note: the semantics of the win32 function FindFirstFile take the
- basename(filename) as a pattern to be matched within the dirname(filename).
- This is contrary to the behavior of the posix function readdir which treats
- basename(filename) as a directory to be opened and read.
-
- For this reason, we append a slash-star or backslash-star to the supplied
- filename so the result is that FindFirstFile will do what we need.
-
- According to the documentation for FindFirstFile, either a '/' or a '\' may
- be used as a directory name separator.
-
- Of course, it is necessary to ensure that this is only done if the trailing
- filespec is not already there.
