Issues

When there was more than one merge conflict automatic cherry pick failed

Solutions

• Use awk to set the Output Record Separator (ORS) to \n, which echo -e in bash can interpret as a newline
• Pipe the output to sed to replace the last \n with \n, to don't end up with an extra newline at the end.
• Move PR_BODY to script to handle properly variable formatting
