Comment:

 Thanks for the report.

 (\ and / are interchangeable in the following)

 OK, the problem is that mingw's stat succeeds for C:\ and C:\foo but fails
 for C: and C:\foo\. The current code strips a trailing \ before calling
 stat.

 I think filepath ought to give us a function to normalise directories in
 this way (normaliseDirectory, perhaps?); what do you say, Neil?

 (incidentally, while experimenting I found that normalise "C:\\" is
 ""C:\\\\", which doesn't seem right).
