Make Range#=== operate like cover? instead of include? for string ranges
Previously, Range#=== treated string ranges that were not endless or
beginless the same as include?, instead of the same as cover?.
I think this was an oversight in 989e07c0f2fa664a54e52a475c2fcc145f06539d,
as the commit message did not indicate this behavior was desired.
This also makes some previously dead code no longer dead. Previously,
the conditionals were doing this:
if (RB_TYPE_P(beg, T_STRING)
if (NIL_P(beg)) # can never be true
This restructures it so at the NIL_P(beg) check, beg could possibly
be nil (beginless ranges).
