* numeric.c (num_step): better iteration condition for float

  values;  suggested by Masahiro TANAKA <masa@ir.isas.ac.jp>.

* range.c (range_step): step (for Range#step method) <= 0 makes no
  sence, thus ArgError will be raised.

* range.c (range_each): Range#each method is special case for
  Range#step(1)

* file.c (rb_find_file): load must be done from an abolute path if
  $SAFE >= 4.

* enum.c (enum_partition): new method. [new]

* re.c (rb_reg_s_quote): quote whitespaces for /x cases.
