glitch in terms documentation (PR#4146)

These are two small items that caught my eye.

I'm looking at the R 1.7.1 2003-06-16 pdf reference manual.  There are
several refences to terms.default (e.g., p. 711, 712) but no definitions
of it.  I'm guessing this means terms, but it's a little puzzling.

Also, the desription of terms.object  does not mention that the
"variables" attribute is actually a list of calls--surprising to me,
since I was expecting text like all.vars.  It would be useful to
indicate if all.vars returns the same ordering as the variables
attribute (at least, I'm wondering it now, though this might be a sign
I've gone astray).

Thanks.
