Thanks for the reminder Ken,

You must have a great memory and/or search strategy.
Even checking back on curl and github I have zero memory of making this patch, 
and it being accepted upstream, but this should prompt me to remember to search 
wider in my email hierarchy, and in my own package repo clones and directories 
for patches.
Now your response is starred in my email.
Perhaps I worked contract gigs too long, my memory compressor kicked in, and 
swapped that out to external storage (here!)
Hoping this will perhaps hammer a nail in my memory to hang that info on.

Cheers!
