[nhc-bugs] A few more minor WinXP problems

[Tony Sloane]

Hi,

Some more that I noticed:

The following resources could not be created.
  The resource 'docs/bugs/Nhc13Test1.hs' could not be created because
another resource exists whose path differs only by case.
  The resource 'docs/bugs/Nhc13Test10.hs' could not be created because
another resource exists whose path differs only by case.
  The resource 'docs/bugs/Nhc13Test13.hs' could not be created because
another resource exists whose path differs only by case.

I think this is all of them.  Again, not a big deal, but it might be
nice to fix.

Cheers,
Tony
