bug#17213: 24.3.50; ruby-mode: misindented continuation method calls inside parens

[Dmitry Gutov]

Example:

abc(foo
     .bar,
    tee
     .qux)

The lines with dots should be indented one column more.

Same if I move either dot to the end of the previous line, but keep the
called methods where they are.

I can fix that for the second method call with the patch at the bottom,
but the first one is unaffected. Not sure what would be the best fix for
it.

On a related note, it's worrisome that indentation of the these two
similar pieces of code in fairly similar positions is governed by
different logic.
