message:
SC2034: $VARNAME appears unused. Verify it or export it.
most of these vars only needed an 'export',
one var ('lexical_url') was really unused.
Ignoring the Chthlulu argument 😃, Route53 returns its XML all on one line, making not possible to grep the hosted zone record with egrep/sed.
This change splits the XML in multiple lines, so that parsing can succeed.
