Fix alignment in generated conf file

[sebb]

I know it's trivial, but it looks odd to have mis-alignment like:

<Location /roster>
PassengerBaseURI /roster
  PassengerAppRoot /srv/whimsy/www/roster
  Options -MultiViews
  CheckSpelling Off
  # SetEnv HTTPS on
</Location>

I think there's a trivial fix:

Change
        content.strip!.gsub! /^#{content[/^\s+/]}/, ' '
to
        content.strip!.gsub! /^\s*/, '  '
at

https://github.com/apache/infrastructure-puppet/blob/deployment/modules/vhosts_whimsy/lib/puppet/parser/functions/preprocess_vhosts.rb#L46

OK?
