Allow multi-level indenting

[aleksip]

@demiankatz This is just a suggestion, so feel free to close without merging if you don't think it is a good change.

Real life use case:

$sources['type'] == 'sectors'
    ? $this->translator
    ->translate('moderation_alert_sectors')
    : $this->translator
    ->translate('moderation_alert_databases'),

Could be indented like this:

$sources['type'] == 'sectors'
    ? $this->translator
        ->translate('moderation_alert_sectors')
    : $this->translator
        ->translate('moderation_alert_databases'),

The related PHP_CodeSniffer documentation has another example.

I understand that the goal is to deviate from the PEAR coding standards as little as possible, but I am not sure if this is covered by them? It seems to be more of a default choice in the PHP_CodeSniffer sniff.

This makes sense to me -- thanks for the suggestion!
