Fix example extraction

Browse Source 
Assumtion was that the first and last lines of examples are always
blank. In 2021/06 the example is only one line. It has no blank line at
the end so the example was deleted by the script.

Changed:
The script will now check if the line is actually blank before deleting
it. Requires that the indentation is removed beforehand.
