"@" isn't being used - and the claim that it's the "canonical" line kill
character doesn't make it less usable; the C preprocessor uses "#" out
the kazoo, but it's the "canonical" character erase character.  (Both of
which were tolerable choices on the local-echoing system they were
originally used on (Multics), but very poor choices on the remote-echoing
system they were moved to (UNIX) - DEC, at least, realized that with remote
echo you can do a lot better, and did!)  (Another point for 4.xBSD, which
supports DEC-style control character handling...)
