kernel-doc: bugfix - empty line in Example section
If you have a section named "Example" that contains an empty line, attempting to generate htmldocs give you the error: /path/Documentation/DocBook/kernel-api.xml:3455: parser error : Opening and ending tag mismatch: programlisting line 3449 and para </para><para> ^ /path/Documentation/DocBook/kernel-api.xml:3473: parser error : Opening and ending tag mismatch: para line 3467 and programlisting </programlisting></informalexample> ^ /path/Documentation/DocBook/kernel-api.xml:3678: parser error : Opening and ending tag mismatch: programlisting line 3672 and para </para><para> ^ /path/Documentation/DocBook/kernel-api.xml:3701: parser error : Opening and ending tag mismatch: para line 3690 and programlisting </programlisting></informalexample> ^ unable to parse /path/Documentation/DocBook/kernel-api.xml Essentially, the script attempts to close a <programlisting> with a closing tag for a <para> block. This patch corrects the problem by simply not outputting anything extra when we're dumping pre-formatted text, since the empty line will be rendered correctly anyway.
