Description of problem:
running ssh-copy-id as a non-admin user returns an error, but seems to complete anyway

Version-Release number of selected component (if applicable):
Fedora 33 KDE

How reproducible:
Consistently

Steps to Reproduce:
1. Install Fedora 33 KDE, standard options
2. create an ssh key with ssh-keygen and accept defaults
3. run `ssh-copy-id -f user@host`

Actual results:
ssh-copy-id throws a warning:
$ ssh-copy-id -f <user>@<host>
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/dmccheyne/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: line 251: warning: here-document at line 251 delimited by end-of-file (wanted `EOF')
/usr/bin/ssh-copy-id: line 250: warning: here-document at line 250 delimited by end-of-file (wanted `EOF')
/usr/bin/ssh-copy-id: line 254: /dev/null`: Permission denied
/usr/bin/ssh-copy-id: line 260: EOF: command not found

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh '<user@host>'"
and check to make sure that only the key(s) you wanted were added.


Expected results:
ssh-copy-id completes cleanly with output like:
Number of key(s) added: 1

Now try logging into the machine, with:   "ssh '<user@host>'"
and check to make sure that only the key(s) you wanted were added.

Additional info:
I've tried a few length keys, and copying keys into the host works ok. I suspect there's just a formatting issue with this block:
  INSTALLKEYS_SH=$(tr '\t\n' ' ' <<-EOF)
        cd;
        umask 077;
        mkdir -p $(dirname "${AUTH_KEY_FILE}") &&
          { [ -z \`tail -1c ${AUTH_KEY_FILE} 2>/dev/null\` ] || echo >> ${AUTH_KEY_FILE} || exit 1; } &&
          cat >> ${AUTH_KEY_FILE} ||
          exit 1;
        if type restorecon >/dev/null 2>&1; then
          restorecon -F .ssh ${AUTH_KEY_FILE};
        fi
EOF
