Fix indentation for comment blocks

[xterao]

When formatting consecutive line comments, indentation is not calculated properly.
Since newline characters are attached to the end of line comments, different control is needed compared to regular newline blocks.
Also, fix the positioning of line comments to align with the element directly below them.

               -- Loop Directive2:Nest1 
                 AND (/*%for emp : employeeList */
                      name = /*emp.name*/'name'
                      -- Condition Directive2:Nest2 Parent : %for : Loop Directive2
                        /*%if true */
                        /*# "AND" */ x = true
                        /*%end */ --Condition Directive2 :END
/** Condition Directive3:Nest2 Parent : %for */
                        /*%if emp_has_next */
                        -- Condition Directive4:Nest3 Parent : %if Condition Directive3
                          /*%if !emp.projects.equals() */

Expected behavior

                 -- Loop Directive2:Nest1 
                 AND (/*%for emp : employeeList */
                      name = /*emp.name*/'name'
                        -- Condition Directive2:Nest2 Parent : %for : Loop Directive2
                        /*%if true */
                        /*# "AND" */ x = true
                        /*%end */ --Condition Directive2 :END
                        /** Condition Directive3:Nest2 Parent : %for */
                        /*%if emp_has_next */
                           -- Condition Directive4:Nest3 Parent : %if Condition Directive3
                          /*%if !emp.projects.equals() */
