	ChangeLog 
Log Message:

	* generic/tclBasic.c (Tcl_CloneInterp): Added code to propagate
	  error messages generated when cloning fails from the clone to
	  the master, for perusal by the code which activated the cloning
	  process. This is especially important to track syntax errors in
	  procedures to clone down. The code was provided by Greg Thompson
	  <gs...@ci...>.

	* generic/tclBasic.c (CloneNamespace): Fixed potential memory leak
	  due to a missing call of "Tcl_DStringFree". Reported by Greg
	  Thompson <gs...@ci...>.

	* generic/tclBasic.c (CloneCommand): Moved code adding the clone
	  to its command table to the end of the command. This makes
	  cleanup in case of a failure easier, there is less to roll
	  back. Added code to release the command strcuture if cloning the
	  procedure structures fails. changed from void to int, returning
	  a TCL_ result code.

	  (CloneNamespace): Changed from void to int, returning a TCL_
	  result code. Now reacting to the result of CloneCommand (and
	  itself), aborts operation in case of a failure.

	  (Tcl_CloneInterp): Now reacting to a failure reported by
	  'CloneNamespace'. Frees the fixup information accumulated so far
	  (via new CloneFixupFree), then deletes the partially created
	  interpreter via the standard 'Tcl_DeleteInterp'.

	  (CloneFixupFree): New function, freeing the fixup information.
