Hi list,
Just a quick demo showing abuse of git's globals:
All I'm doing here is accepting a patch I made on a 
Windows machine that forced me to enter a user 
name and email addy in order to do a commit.
git has the good sense to punt on the question 
of secure identity management-- it lets you use 
pretty much any garbage you want and assumes 
the humans behind the screen will separate wheat 
from chaff.
However, the user-friendly tools that wrap around 
git (github, gitlab, etc.) don't make this clear as you 
can hopefully see. :)
