Indeed it would. Done.

True. The user most likely is not going to run 'git help $x > output'.

Initially I was making a boolean, but stopped when I found
color.pager. Since Jeff said to use want_color() in the same way all the
other color.* configurations, I forgot, and used a colorbool.

I've returned back to a bool, and updated the documentation.

color.ui=auto is still respected (if stdout is a tty color is disabled),
but it doesn't really matter because less seems to be smart and disable
color anyway.

v3 sent.
