When parsing the expression

  A + B + C
									       
with the grammar in the Addendum on Parsing Expressions,
you must continue after you see that A is a [term];
otherwise you could not parse the entire expression.

Similarly, when you see a [local] you must continue
until you find something that cannot be part of a
[prefix].
