git-send-email invokes the cc-cmd like this:

    $cc-cmd $patchfilename

so, when you used 'cat cc-cmd' as the value of --cc-cmd, your invocation became:

    cat cc-cmd $patchfilename

and since 'cat' copies the concatenation of its input files to its
output, that explains why you first saw the names from your 'cc-cmd'
file followed by the content of the patch file.

A quick-and-dirty work-around is to use '#' to effectively comment out
the patch file name:

    --cc-cmd='cat cc-cmd #'

which works, but is very, very ugly.

Nope.

A very simple working solution is to make your 'cc-cmd' file executable:

    #!/bin/sh
    echo <<\EOF
    person1@example.com
    person2@example.com
    EOF
