Yes, that's used fairly often in the pattern

 save <- options( <something new> )
 on.exit(options(save))

Looks like it.  ?par, which uses similar syntax, documents ... as

     ...: arguments in 'tag = value' form, or a list of tagged values.
          The tags must come from the graphical parameters described
          below.

as opposed to ?options, which leaves off the "or a list" part.
