Be better about bounds-checking, #'subseq, #'fill; add same, #'reduce. 2010-09-16 Aidan Kehoe <kehoea@parhasard.net> * fns.c (Fsubseq): Change the string code to better fit in with the rest of this function (it still uses get_string_range_char(), though, which *may* diverge algorithmically from what we're doing). If dealing with a cons, only call #'length if we have reason to believe that the START and END arguments are badly specified, and check for circular lists ourselves when that's appropriate. If dealing with a vector, call Fvector() on the appropriate subset of the old vector's data directly, don't initialise the result with nil and then copy. (Ffill): Only check the range arguments for a cons SEQUENCE if we have good reason to think they were badly specified. (Freduce): Handle multiple values properly. Add bounds checking to this function, as specificied by ANSI Common Lisp.
