We've certainly found, and fixed, similar issues within Exim in the
past. A hunt turned up 99ab56234b, at least - but that's the other
side of the coin: dealing properly with received line-wraps at
awkward places.

As far as avoiding producing such in lines generated by Exim,
I'd argue against changes unless we're producing out-of-spec
ones, because we'd be as likely to break some other implementation
as to "fix" the broken one.
