bug#15782: 24.3.50; common-lisp-indent-function for with-compilation-unit

[Helmut Eller]

By default, common-lisp-indent-function indents with-compilation-unit
not very nicely. E.g.:

  (with-compilation-unit (:option1 foo
                                   :option2 bar)
    x)

With the patch below it will look better, like so:

  (with-compilation-unit (:option1 foo
                          :option2 bar)
    x)
