Squiz.Commenting.FunctionComment fatal error when fixing additional param comment lines that have no indent

[louisl]

I'm getting a PHP Fatal error with phpcbf using.
<rule ref="Squiz.Commenting.FunctionComment"/>

I've narrowed it down to 'SpacingAfterParamName' so If I remove that, the file fixes.

<rule ref="Squiz.Commenting.FunctionComment.SpacingAfterParamName">
    <severity>0</severity>
</rule>

Obviously the commenting here's a bit of a mess missing params etc.;)
There's a bunch of this going on in this file so I've condensed it down to show the issue.
$ phpcbf --standard=Squiz test.php

test.php

This was caused by fixing code that tries to adjust the indent of additional lines in a param comment after fixing the first line. In this case, the additional lines have no indent, so the adjustment (-2 spaces) ends up making the indent negative. Now, the sniff wont adjust the indent of those lines if they are not indented far enough.

Thanks for the report.
