regex <-match: in=char_array|text_buffer|fragment, start=[int], end=[int] -> length=int
Match the regular expression's regex<-pattern with the given object. The match starts at start (default 0) and should not pass end (default end of the object matched). The regex<-match variant returns the number of characters matched. For both methods, regex<-register_start, regex<-register_value, etc. may be used afterwards.
