tagging to PayloadSearchNocase() will show you that it applies only to
the last PatternMatchData structure, setting its search method to
uniSearchCI() (a default of uniSearch is provided in ParsePattern).
incidently, this iterating code appears to have been cut-and-pasted from
PayloadSearchDepth(); PayloadSearchOffset() shares the same, although
lacking the dubious c++ style cast from void *. a bit of a mess, that.
