Summary: clarify/change [dict set] specification 

Initial Comment:
Hi,

I would like to suggest that the specification of "dict
set" should be clearer with regard to missing
sub-dictionaries: the question is what 

   dict set dictVar $k1 $k2 ... $kn $value  

should do if the sub-dictionary for the key sequence
$k1, ..., $k{n-1} does not yet exist in $dictVar. I
suggest that such sub-dictionaries are silently created
as needed.

(A recent related discussion can be found on the
Tcl'ers Wiki page for the dict command.)

I'm not at all sure that magical creation is a good idea (it
can conceal stupid bugs of the "hit the space key in the
wrong place" variety, which I know *I* am inclined to make!)
but I'll review the TIP and the documentation to be sure
before commenting further.
