Adding test for second doxygen comment style

This style looks like:

/** Line 1
 *  Line 2
 */

This is needed to verify fixes to some of the indentation in the
translated comments.

The test is copied from doxygen_basic_translate.i.  One adjustment was
made to change the comment style on the last function that left out
the intermediate "*" characters.  This does not produce correct output
when combined with this style of starting the text on the first
comment line.

Test results are copied directly from doxygen_basic_translate.  A
minor difference in the Python results will be updated in a subsequent
commit.
