[ESS] github flavor

[Tyler Smith]

Hi Stephen,

What does `C-h f poly-gfm+r-mode` tell you?

For me, it reports "poly-gfm+r-mode is an interactive Lisp closure 
in ‘poly-R.el’."

I wonder if your version of poly-R.el doesn't include this? If 
you've installed from melpa stable (i.e., 
"https://stable.melpa.org/packages/"), you'll have the version of 
poly-R from March 2020, which doesn't include the gfm flavour. The 
melpa version from "https://melpa.org/packages/" should work.

Best,

Tyler
