    David,

    I think the short answer is "there is no standard answer, different
    tagging projects and tagged corpora adopt different policy on corrections
    and tokenisation". For example, see

    Atwell E, Demetriou G, Hughes J, Schiffrin A, Souter C, & Wilcock S. 2000.
    A comparative evaluation of modern English corpus grammatical annotation
    schemes. to appear in ICAME Journal, vol.24.

    Even if you are using existing guidelines (you mention Penn Treebank) you
    need not be bound by them if you have good reason to modify them for your
    specific text genre (as long as you document your decision in your Corpus
    Handbook); after all, this is what other corpus-tagging projects have
    done.
