Thanks Ammar.  Curiously, the comment I had put in my code was a note 
regarding usage and actually didn't contain the word "coding:" but the 
word "encoding:".

# curl -v --header "Transfer-Encoding: chunked" -d @somefile.txt 
"http://localhost:80/"

Perhaps this is a slightly different kind of bug in that the interpreter 
doesn't regex /[^a-zA-Z]coding:/ .  Or a documentation bug. ;)
