Indentation bug in multi-line function call with split strings

[cweiske]

When a function call contains a string parameter split onto multiple lines, there is an indentation problem:

<?php
myfunc(
    'pages',
    'foo'
    . 'bar'
        . 'baz'
);

The baz line should be indented in the same way as the bar line.
I myself prefer it on the same indentation level as the initial string line. I couldn't find a rule for that in PSR-2 nor PSR-12.

This problem appears in the following styles (C-c .):

• drupal
• pear
• psr2
• symfony2

Problem does not appear in:

• wordpress
• php
