Summary: Tcl_VarSetResult()

Initial Comment:
It would simplify composite error message generation a 
bit if there were an exposed analog to Tcl_AppendResult
() that first reset whatever result was currently in the 
intepreter (if any).

e.g.:

Tcl_VarSetResult(interp, "The value '", pName, "' is an 
invalid name for a record of this type.", NULL);

versus:

Tcl_ResetResult();
Tcl_AppendResult(interp, "The value '", pName, "' is an 
invalid name for a record of this type.", NULL);

or:

Tcl_SetResult(interp, "The value '", TCL_STATIC);
Tcl_AppendResult(interp, pName, "' is an invalid name 
for a record of this type.", NULL);

or implementing a wrapper like Tcl_VarSetResult() in 
each application where such error messages are being 
generated.

I think TIP 270 essentially
satisfied this.

Take note of the internal
TclObjPrintf() function in
Tcl 8.5.  With good review,
it could be made public.

See http://wiki.tcl.tk/12975 for a sprintf-type command to
create a Tcl_Obj string

While we're at it, let's have one that behaves like
sprintf(); there's all sorts of places where that'd be
useful!
