Summary: small Tcl_MakeFileChannel issue

Initial Comment:
:Windows

If you create a namedpipe which only uses one handle
for both read and write and give it to 
Tcl_MakeFileChannel(), a problem arises when the
channel is closed because the close2proc is set to
think read and write are 2 different handles and
closes each of them.  This goes *boom* :)

Attached is a patch that I think fixes this.

The core does not used namedpipes anywhere, but I
found this issue while working on Expect.

Do we have tests in the testsuite with which we can check 
that that this change does not break things ? I looked at 
it and do not believe that it does break anythings, but I 
would like to check.
