Log Message:

	* generic/tclIO.h (CHANNEL_INCLOSE):       New flag. Set in
	* generic/tclIO.c (Tcl_UnregisterChannel): 'Tcl_Close' while the
	* generic/tclIO.c (Tcl_Close):             close callbacks are
	  run. Checked in 'Tcl_Close' and 'Tcl_Unregister' to prevent
	  recursive call of 'close' in the close-callbacks. This is a
	  possible error made by implementors of virtual filesystems based
	  on 'tclvfs', thinking that they have to close the channel in the
	  close handler for the filesystem.

	* generic/tclIO.c:
	* generic/tclIO.h:
	* Not reverting, but #ifdef'ing the changes from May 19, 2004 out
	  of the core. This removes the ***POTENTIAL INCOMPATIBILITY***
	  for channel drivers it introduced. This has become possible due
	  to Expect gaining a BlockModeProc and now handling blockingg and
	  non-blocking modes correctly. Thus [SF Tcl Bug 943274] is still
	  fixed if a recent enough version of Expect is used.

	* doc/CrtChannel.3: Added warning about usage of a channel without
	  a BlockModeProc.
