This addresses #1941.

18d0a74f23 MODIFIED: read_line_to_chars/3 is now called get_line_to_chars/3 
This is for consistency with other I/O predicates, where "read" always
indicates Prolog terms. Please adjust your programs accordingly.

8b7281fad0 ADDED: dif_si/2 
Source: https://stackoverflow.com/questions/20223390/prolog-a-person-is-a-sibling-of-himself

In Scryer Prolog, this is actually not needed, since Scryer Prolog provides
dif/2 in library(dif). However, it is still useful to provide dif_si/2 for two reasons:

  1) to more easily port code from systems where only dif_si/2 is available
  2) to provide correct disequality in other systems that adopt this library

       false.
