43904 (plus tweak): zshmisc(1): document term being optional if `in word' is omitted

In code such as:

> hobbes% () { for arg do print -r $arg; done; } 1 2 3
> 1
> 2
> 3

the implicit positional parameters added when the `in word ...'
list is omitted also implicitly append the separator term, making
the above code valid, albeit seemingly violating the syntax listed
in the documentation.

This is related to the various forms of alternative syntax and is
the intended behavior of the parsing code, so correct the minor
contradiction in the for loop documentation.

 More than one parameter var(name) can appear before the list of
 var(word)s.  If var(N) var(name)s are given, then on each execution of the
 loop the next var(N) var(word)s are assigned to the corresponding
