System tests: tighten 'is' operator

Fix day-one sloppiness: when I first wrote this framework
it compared strings using 'expr', not '=', to be more
forgiving of extra cruft in output. This was a bad decision.
It means that warnings or additional text are ignored:

    is "all is ok, NOT!"  "all is ok"  <-- this would pass

Solution: tighten up the 'is' check. Use '=' (direct
compare) first. If it fails, look for wild cards ('*')
or character classes ('[') in the expect string. If
so, and only then, use 'expr'. And, thanks to a clever
suggestion from Luap99, include '(using expr)' in the
error message when we do so; this could make it easier
for a developer to understand a string mismatch.

This change exposes a lot of instances in which we weren't
doing proper comparisons. Fix those. Thankfully, there
weren't as many as I'd feared.

Also, and completely unrelated, add '-T' flag to bats
helper, for showing timing results. (I will open this
as a separate PR if requested. I too find it offensive
to jumble together unrelated commits.)
