To avoid consuming space on the C stack, \fITheCmdOldObjProc\fR is renamed to
\fITheCmdNRObjProc\fR and the postprocessing step is split into a separate
function, \fITheCmdPostProc\fR, which is pushed onto the function stack.
\fITcl_EvalObjEx\fR is replaced with \fITcl_NREvalObj\fR, which uses a
trampoline instead of consuming space on the C stack.  A new version of
\fITheCmdOldObjProc\fR is just a a wrapper that uses \fBTcl_NRCallObjProc\fR to
call \fITheCmdNRObjProc\fR:
.PP
.CS
int
\fITheCmdOldObjProc\fR(
    void *clientData,
    Tcl_Interp *interp,
    Tcl_Size objc,
    Tcl_Obj *const objv[])
