Dropping the patch.

Like we do any other code review: use common sense and follow established best
practices.  If a human reviewer pointed out an existing bug, we would analyze
the situation and make a judgment call as to whether it's better to send a
standalone fix or roll a fix into a new version of the series.  If we decided to
fix the issue separately, and then a human brought up the same pre-existing issue
in a future revision, we would point them at the fix or the previous discussion
(or if it was the same human, (politely?) tell them to go away).

The only differences is that Sashiko is noisier because is doesn't (yet?) remember
what feedback it gave in the past, often doesn't look at the patches later in the
series, and doesn't (yet?) respond to emails so telling Sashiko to shut up about a
particular pre-existing issue isn't effective.

But to be very explicit: don't include a patch *purely* to suppress Sashiko's
rediscovery of existing issues.
