- updated to PCRE 6.1

        The original PCRE 6.1 sources are checked into the tree with the tag
        "pcre-6-1" for reference. What we're checking in right now is the original
        plus our changes to make it support UTF-16 and at least one other tweak
        (vertical tab considered whitespace). Our work to get our changes was
        done on "pcre-6-1-branch", with an anchor at "pcre-6-1-anchor" so you can
        see the evolution of the UTF-16 changes.

        Note also that there was one small change made here that's not on the branch
        in pcre_compile.c.
