Bug: Cromwell removes empty spaces from WDL when creating exec.sh

This doesn't sound like a bug, but it means that the following task is edited prior to submission:

workflow hello {

    call HelloWorld{}

}

task HelloWorld {
    command{
        echo "hello

        and

        goodbye."

        cat <<EOF
        Line1

        Line2

        Line3
        End
        EOF

    }

    runtime {
      docker: "python:2.7"
      memory: "1 GB"
    }

    output {
        String out = read_string(stdout())
    }
}

The resulting exec.sh is:

#!/bin/bash
tmpDir=$(mktemp -d /cromwell_root/tmp.XXXXXX)
chmod 777 $tmpDir
export _JAVA_OPTIONS=-Djava.io.tmpdir=$tmpDir
export TMPDIR=$tmpDir

(
cd /cromwell_root
echo "hello
and
goodbye."
cat <<EOF
Line1
Line2
Line3
End
EOF
)
echo $? > /cromwell_root/HelloWorld-rc.txt.tmp
(
cd /cromwell_root

)
sync
mv /cromwell_root/HelloWorld-rc.txt.tmp /cromwell_root/HelloWorld-rc.txt

which is missing the empty lines I wanted to have in my "echo" and "cat" commands!

My guess is was considered a feature that by removing the empty lines you can be agnostic to them during call-caching, but this insiduous: it makes it difficult to have empty lines in strings in one's methods. I consider this overly intrusive and would rather have a new-line edit invalidate call-caching than be subjected to manipulation of my carefully crafted command-block.

Removing empty lines can cause other

command<<<
echo hello \

echo goodbye
>>>

will either result in
"hello echo goodbye"
or in
"hello
goodbye"

Depending on that empty space....(you might argue that the author should have removed the training '\' and I would argue back that my coding style is none of your business....)
