Good idea.  No patch for this, though, because it would require quite
a bit of coding -- so much that I'm actually reluctant to try it at
all.  Think about the need to be able to find out which word is a name
and which is a value, think about optional values -- that would almost
require a re-implementation of the C-core of _arguments.  Urgh.

It may actually be easier to leave _values for handling only things
expressable in a single word and changing _arguments to handle
`options' without leading `-'s or `+'s.

Or rewrite both of them, based on a bit of common code.  Some parsing
front ends (one for multiple words, one for a single word) producing
the same internal format which is then used by a common back end.  Hm.

I made that because that description isn't always needed (not when one
of the actions is used) and I wanted to avoid superfluous calls to
_description.
