* src/spec.sh
(__spec_result): Remove variable.
(__spec_outfile): Add variable.
(expect): Write stdout to temporary file rather than storing in variable,
which strips trailing whitespace and does not handle null bytes.
(shspec::__handle-to): Use `$__spec_outpath'.
Update copyright years.
* test/test-spec: Add tests for trailing whitespace and binary comparison.
This is motivated by Google's shell coding standards and will reduce the
odds of a naming conflict with other functions (which, of course, would
cause terribly odd and difficult-to-find bugs, in both our system and
others').
If this seems like it creates long, overly-verbose function names with no
relief in sight---you're right. I'll have a solution for that in a bit, as a
separate project. ...as a part of my never-ending, growing heap of projects.
