If SET allows it, I guess we can allow it here.  But is a grammar change
really all that is needed to make it work from the file?

That seems like a seriously bad idea.  I note that SET does *not* allow
this; furthermore it seems like a considerable weakening of our ability
to detect silly typos in config files.  Nor did you offer a use-case
to justify it.
