As I mentioned on the patch itself, I'd prefer if Git didn't do this.  I
have my own colors configured and don't want Git to render its man
output differently from what I have.  Even if I didn't, I wouldn't want
Git to change the output of man(1) to be different from what's on the
system.

I should point out that I have my shell configuration set up to use
different colors depending on the capability of the terminal, such as
using a 256-color palette when that's supported and a 16-color palette
when it's not, so there is literally no configuration that Git can
provide here that matches my existing settings.

Additionally, colors tend to pose accessibility problems for a lot of
people.  I have normal color vision, but because I use a transparent
background which renders as grey, the standard terminal red is nearly
illegible for me.  I also know people with colorblindness who have
problems with various colors or any colors at all.
