See the post at https://mail.gna.org/public/relax-devel/2007-07/msg00037.html for the patch.
This patch (patch__function_spacing__1.3_r3341) fixes function spacing formating
issues in the 1.3 line (r3341). The convention is to leave two empty lines
before a function definition. The issues were found with the code_validator
script and filtered so that when a function definition followed a class
docstring or class variable, only one empty line is left instead of two.
