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.
