Yeah, I think this needs separate treatment. However, this is a perfect
example of the "case-by-case" I mention in the final two paragraphs
there.
What's the right encoding to be grepping in? The original, what we will
output in, or even something else? IOW, I wonder if this should be using
logmsg_reencode in the first place (the obvious reason not to want to do
so is speed, but logmsg_reencode is written to only have an impact in
the case that we do indeed need to reencode).
