Unlike the LESS_TERMCAP_* strategy, this completely breaks "git help" on my system:

  $ ./git help git
  There is no -D option ("less --help" for help)

  $ man less | grep -A1 '^ *-D'
         -Dxcolor or --color=xcolor
                [MS-DOS only] Sets the color of the text displayed.  x is a single

This is less 551-2 on Debian unstable.
