Subject: Add a hack to work around some issues with remote debugging with
 Xcode.  Xcode requires that stdin & stdout be closed or you won't be able to
 interrupt the running program.  So I added a check for XCNOSTDIN environment
 variable in the startup, and I force them closed if it is set.  With that,
 remote debugging works pretty well.

+- If you want to use Remote Debugging with Xcode 1.5 or 2.0, then you need to set
+the environment variable XCNOSTDIN to 1 in the Executable editor for Wish Shell.  That
+will cause us to force closing stdin & stdout.  Otherwise, given how Xcode launches
+Wish remotely, they will be left open and then Wish & gdb will fight for stdin...
