Style/MultilineOperationIndentation doesn't catch lines ending in \

[mockdeep]

When I wrap strings with \ the MultilineOperationIndentation style check doesn't flag them when they are misindented. The following string passes checks:

      flash[:error] = 'Here is a string ' \
                      'That spans' <<
        'multiple lines'

Side note, it also allows << for multi-line strings. I'll add another issue for that.

Additionally, I'm using the rule with EnforcedStyle: indented.

Another side note, when I change the \ to a + it fails both checks.

@jonas054 Likely the same problem as in #1474 (the concatenated string is a dstr node without beg/end).

It certainly looks like it. I'll try to fix it.

It turned out to be a different problem.
