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.

I see.

Looking at their history it seems they only enabled this for non-MS-DOS
builds in 2021.

That explains why most people haven't found this yet, and are using
LESS_TERMCAP_*.

I'll revert back to LESS_TERMCAP_ and test with an ancient version of
less.

Thanks for testing.
