 * Test that strings only consisting of a number are quoted to prevent
 * consumers from interpretting them as a number and thus mangling the
 * string value by normalizing the number.
 * Ability to quote numerical strings at each part of a YAML document is
 * tested in tests for the particular document type, i.e. not in this file.
 * This code uses an RPM package list of a stream profile for the purpose
 * of testing. It's the most brief usage of quoting.
