Proposed patch and new testcases

I'm not comfortable self-approving this patch; the option processing code is
totally new to me and I have no idea if I got it right.  And while I believe
the sense of -Wuninitialized is correct (no change in current behavior), I
don't think we have reached a consensus on that issue.

I will note that after reviewing all the PRs, by far the most common complaint
is false positives,  #2 is missing warnings, particularly for objects which
have had their address taken, #3 is missing warnings in unreachable/dead code
(which we can now detect with -Wuninitialized=2 using this patch).
