$^! is $! with the RC_EXPAND_PARAM option turned on.  Try this:

$ sleep 10 &
$ cat <<EOF
Enew    line    here
G@#$^!@#=&
EOF
Enew    line    here
G@#24108@#=&
   ^^^^^
   Note process ID here

It might be possible for zsh to special-case use of the ^ modifier, but
really the cvs test should be using a quoted here-document, like so:

cat <<'EOF'
Enew    line    here
G@#$^!@#=&
EOF

This should work correctly in bash, ksh, and sh, as well as zsh.
