Fix proposal for # 3515 
OK I've deleted the unnecessary commented lines and left the option that feed only the description tooltip. 

BTW, I have 2 questions i would like to ask you
1. about comment, i noticed there are not many comments in the code. I understand it is deliberate choice of design, is it ? 
I usually comment a lot inside  the code sometimes simply to order my thoughts and remember what the code is intending to do when i come to it later on. 
I understand it is better not to leave unneccessary  lines like here, but in general, do you prefer me to avoid comments when writing in blenderbim ?    

2. As i'm in a discovering phase, I would like to feed some other bl_description operators to provide some additionnal inline information instead (undocumented operator) , is it something you planned or can i go for it. I could simply add the bl_description in each one i find while reading code and testing app.    

Thank you for your kind help. and G'day !
