I'm not sure, whether it works under any circumstance. For example:
$ cat <<EO\
> F
> xxx\
> yyy
> EO\
> F
> EOF
xxxyyy
EOF
$
The heredoc does not understand the first EOF, when written as
EO\
F
Granted, that is malicious example. But it shows we need some knowledge
about the string, and where to add \\n.

grep.el doesn't know it either. But it knows more about the arguments,
and where to add that line break.
Best regards, Michael.
