You need to run TclX to see this bug, but the callback made via
Tcl_CreateTrace passes in a command argument that is no longer
null-terminated at the end of the command.  Instead you see the
rest of the script.  This probably occurred in the effort to
remove "null hammering".

To see, take this script:

proc someProc {} {}

cmdtrace on noeval
someProc
someProc
someProc
cmdtrace off

And run it from the command line with Tcl X:

./tcl trace.test
 1:  someProc\nsomeProc\nsomeProc\ncmdtrace off\n
 1:  someProc\nsomeProc\ncmdtrace off\n
 1:  someProc\ncmdtrace off\n
 1:  cmdtrace off\n

In this simple case, the string should terminate at the \n



This has been broken since 8.2, we think.  It would be nice to fix
for Tcl 8.3.2 and TclPro 1.4
