message:
SC2034: $VARNAME appears unused. Verify it or export it.
most of these are related to the style:
we generate global vars, which are used in other functions.
the var "lexical_url" was really unused (left it as comment)
the travis-check now does not need anymore special flags.

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.
