I thought of a simple way to address that objection for this particular
case: we can just truncate the context display *at* the offending
character, instead of *after* it.  This is playing a bit fast and loose
with the general principle that the context should end at the point of
detection of the error; but given that the character in question is
always unprintable, I think it's probably not going to bother anyone.

I've gone ahead and committed this before branching, though I'm
certainly still willing to entertain suggestions for further
improvement.
