This adds Alert annotations for alerts that seem intentional by the test
but has not been annotated with 'NOT OK', or the comment was in the wrong
place.
In a few cases I included 'Source' expectations to make it easier to see
what happened. Other 'Source' expectations will be added in bulk a later
commit.
Some OK-style comments had to be moved to the following line, shifting line numbers.
In selected range also included the comments themselves.
Lastly, the result sets were reordered by the CLI in some cases.
These were originally meant to give you the term that is textually matched right before/right after the receiver. When I introduced support for lookbehinds, I changed the behaviour to give you the term that is _operationally_ matched before/after the receiver (remember that lookbehinds are implemented by reverse-matching).
However, I think that's rarely ever what you want, and is wrong for the only two uses of these predicates, where it's the textual matching order that we are after, not the operational order.
Consequently, I've changed the semantics back and updated the comments to hopefully clarify the intention.
