No, if the parser is restricted, there should be no need to "widen" it, at least not in most cases I could think about where a parser should be restricted to a part of the buffer. > Anyway, I don't see why we should institute a special category for these > buffers.

Which first paragraph is that? In what "previous reply" should I look and where?

I'm "quibbling" over words because your particular selection of words makes serious discussion nigh impossible. Not the first time, either. As soon as there's some disagreement, sooner or later those words (like "quibbling") come out. Whether it's because of some attitude or not, I don't know, but you may wish to reflect on that and perhaps try to express your disagreements using different words.
