Description:
bash -D doesn't parse $"translatable messages" inside heredocs.
Heredocs are nice for usage() functions and other cases,
it'd be nice for bash -D to support them.

Repeat-By:
Create the following script:

#!/bin/bash
cat <<EOF
$"message1"
$(echo $"message2")
EOF

Run bash -D script, it produces no output.
