Move #'replace to C, add bounds-checking to it and to #'fill. 2010-09-06 Aidan Kehoe <kehoea@parhasard.net> Move #'replace to C; add bounds checking to it and to #'fill. * fns.c (Fsubseq, Ffill, mapcarX): Don't #'nreverse in #'subseq, use fill_string_range and check bounds in #'fill, use replace_string_range() in #'map-into avoiding quadratic time when modfiying the string. * fns.c (check_sequence_range, fill_string_range) (replace_string_range, replace_string_range_1, Freplace): New functions; check that arguments fit sequence dimensions, fill a string range with a given character, replace a string range from an Ibyte pointer.
