Beginless ranges previously raised TypeError for this case,
except for string ranges, which had unexpected behavior:
('a'..'z').include?('ww') # false
(..'z').include?('ww') # previously true, now TypeError
Use of include? with endless ranges could previously result
in an infinite loop.
This splits off a range_string_cover_internal function from
range_include_internal.
Fixes [Bug #18580]
Previously `(2..).cover?("2"..)` was false, but
`(..2).cover?(.."2")` was true. This changes it so both are false,
treating beginless ranges the same as endless ranges in regards to
type checks.
This also adds documentation to #cover? to describe behavior with
beginless and endless ranges, testing each documentation example,
which is how this bug was found.
Fixes [Bug #18155]
Previously, include? would return true for the end of the range,
when it should return false because the range is exclusive.

Fixes [Bug #18577]
I used this regex:
([A-Za-z]+)\.html#(?:class|module)-[A-Za-z]+-label-([A-Za-z0-9\-\+]+)
And performed a global find & replace for this:
rdoc-ref:$1@$2
In commit:7817a438eb1803e7b3358f43bd1f38479badfbdc, the implementation
of `Time#succ`, which had been deprecated for 10 years, was finally
removed.
During that time, there was an explicit `instance_of?` check in
source:range.c#L350 with a comment that the check should be removed
once `Time#succ` is removed.
Since `Time#succ` is now gone, this check should be removed.
Note: this should be coordinated with adding a version guard to the
corresponding check in ruby/spec as well.
* As the "doc/" prefix is specified by the `--page-dir` option,
remove from the rdoc references.
* Refer to the original .rdoc instead of the converted .html.
* Support ArithmeticSequence in Array#slice
* Extract rb_range_component_beg_len
* Use rb_range_values to check Range object
* Fix ary_make_partial_step
* Fix for negative step cases
* range.c: Describe the role of err argument in rb_range_component_beg_len
* Raise a RangeError when an arithmetic sequence refers the outside of an array
[Feature #16812]
Popular Ruby libraries such as Rails and Rubocop relying on the
previous behavior, even though it is technically a bug. The
correct behavior is probably raising RangeError, since that is what
an endless range raises.
Related to [Bug #17017]
Previously, for inclusive ranges, the max would show up as the
end of the range, even though the end was not an integer and would
not be the maximum value. For exclusive ranges, max/minmax would
previously raise a TypeError, even though it is possible to get the
correct maximum.
This change to max/minmax also uncovered a similar error in cover?,
which calls max in certain cases, so adjust the code there so that
cover? still works as expected.
