Someone else will need to check this, I don't use mu4e.  But I don't
expect surprises, as the issue I fixed was quite clear and simple to
fix.

Yes, what I saw in your test file is quite crazy.  Making the
beginning of a line invisible in a buffer that truncates line is about
the worst atrocity one can commit against the display engine.  And
then all those eight-bit bytes (presumably used as markers for
something?) in the invisible part... shudder.
