I have to apologize.
My review on the v1 of this patch suggested that a value like "0 "
was possible in the setter functions in dict.c. I double-checked the
parser code, and that was wrong. The parser already strips trailing
whitespace. We actually have a test for that in tests/parser.c
(test04).
So, I have to say I actually prefer the v1, which was leaner and worked
just as well as this one. My concern was that you didn't set any value
(relying on the previously-set default), but you've convinced me that
that was ok.
So, if you don't mind, I'll put my "Reviewed-by" on the v1 of this
patch.

Martin
