Directory.doesDirectoryExist inconsistency

[Simon Peyton-Jones]

Sigbjorn (and others interested in Win32 I/O behaviour)

The fact that MS CRT differs from Unix doesn't mean that the Haskell
interface should necessarily differ.  The Haskell impl of
doesDirectoryExist could, on Win32, trim off trailing '/' or '\', in
order to make the behaviour consistent.  Where it's possible to get
consistent behaviour, we should strive for that.  Do you agree?

| This is known behaviour of the MS CRT implementation

| Undesirable behaviour, you might (reasonably) say, but
| the format of FilePaths is left system-specific by Haskell98.
