Previously, the following stanza would fail as a result of the
ini_setting type not being able to parse spaces in setting values.
ini_setting { 'main_config_version':
ensure => present,
path => '/etc/puppetlabs/puppet/puppet.conf',
section => 'main',
setting => 'config_version',
value => '/etc/puppetlabs/puppet/config_version.sh $environment',
}
This commit modifes the SETTING_REGEX to account for spaces in setting values.
This commit does the following:
* Fixes a bug in ExternalIterator
* Adds support for a "global" section before the first named
section at the beginning of the INI file
* Improves test coverage
