[Doxygen-develop] Enabling/disabling line numbers for \example listings

[Karl R. <me...@ka...>]

Hi,

a patch for enabling/disabling line numbers in \example listings is 
attached. Using the switch
   EXAMPLE_WITH_LINES = [YES/NO]
one can now toggle line numbers. The default is 'NO' in order to be 
consistent with the current behavior.

Best regards,
Karli
