Jeremy Evans f4394bbca3 Do not autosplat when calling procs that accept rest and keywords
When providing a single array to a block that takes a splat, pass the
array as one argument of the splat instead of as the splat itself,
even if the block also accepts keyword arguments.  Previously, this
behavior was only used for blocks that did not accept keywords.
