--------------------------------

taking out of PA. on second thought I'd rather not alter so much of table.rb

> Feedback from [~mdrob] on HBASE-19158:
> {quote}
> Shell:
> HBASE-19770. There was another issue opened where this was identified as a problem so
maybe the shape will change further, but I can't find it now.
> {quote}
> New commentary from [~busbey]:
> This was a follow on to HBASE-15965. That change effectively makes it so none of our
ruby wrappers can be used to build expressions in an interactive REPL. This is a pretty severe
change (most of my tips on HBASE-15611 will break, I think).
> I think we should
> a) Have a DISCUSS thread, spanning dev@ and user@
> b) based on the outcome of that thread, either default to the new behavior or the old
behavior
> c) if we keep the HBASE-15965 behavior as  the default, flag it as incompatible, call
it out in the hbase 2.0 upgrade section, and update docs (two examples: the output in the
shell_exercises sections would be wrong, and the _table_variables section won't work)
> d) In either case document the new flag in the ref guide
