git -c color.man=false help -m" would let you consume the output in
any way you want, I would presume?

Yes, accessibility issues are real.  But a bit of configuration to
disable colors would rescue our users.  I work on white-background
with black pixels, and colored diff output that shows lost lines on
the same background with red pixels is hard to read for me, but
thanks to color.diff.<slot> settings, I can customize it to draw in
reverse colors.
