char * *foo;

When we are detecting whether a comment is open when we start a hunk we
check for the first comment edge in the hunk and assume its inverse.
However if the hunk contains something like below, then we will assume
that a comment was open. Update this heuristic to see if the comment edge
is obviously within double quotes and ignore it if so:
foo(" */);

When reporting some complex trailing statements we report only the
starting line of the error, that tends to imply the shown line is in error
and confuse the reader. As we do know where the actual error is report
that line too with an appropriate gap marker where applicable.
