REDUCE/into of non-block doesn't insert into target

[rebolbot]

Submitted by: BrianH

REDUCE/into is supposed to insert its resulting value(s) into the target block specified by the out parameter. However, the /into option is ignored when the value argument isn't a block, and REDUCE just returns value as if /into wasn't specified. REDUCE/into should always insert.

>> head reduce/into "a" []
== "a"  ; should be ["a"]

Had been "resolved" in Ren-C, but there was a bug and no test. Bugfix and a test added:

EDIT: Resolved in Ren-C because it has eliminated the /INTO feature, explanation here
