* string.c (rb_str_upto): generate sequence according to "succ"
order. formerly check was done by dictionary order. [ruby-talk:74138] * string.c (rb_string_value): fill constant empty string along with setting ELTS_SHARED if str->ptr is NULL. [ruby-core:01179] * string.c (rb_string_value_ptr): ditto. * string.c (rb_check_string_type): ditto. * string.c (str_gsub): move END(0) check before mbclen2(). * string.c (scan_once): reduce END(0) check. * io.c (rb_io_initialize): accept fixnum mode. * eval.c (error_print): replace strchr() by memchr(), einfo may contain "\0". * pack.c (pack_unpack): range check for "@" move; initialize check for "m". * error.c (syserr_initialize): avoid buffer overflow. * file.c (rb_file_s_readlink): expand buffer until readlink succeed. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@3982 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
