Re: Disable Mouse Wheel Progressive Speed Patch

[Sarah Sunday]

That’s fascinating. Until it’s been fixed, I definitely think we should disable 
it as, Tak said, it is really troublesome to use out of the box. 

Even after the fix has been implemented, I would say keep it default off as it 
really feels like something the user would need to configure to compliment 
their mouse resolution/set-up instead of Emacs assuming for them. But that 
bridge can be crossed when it gets to that point.
