* less: enable by default and set LESS=-R via lesskey
* since we set PAGER=less, programs.less.enable should default to
true.
* some programs, notably git, set a custom LESS environment if none is
present. using the lesskey mechanism to set LESS=-R lets such
programs continue to run less as they see fit.
This reverts commit 0e7b4e60a8.
* less: remove use of deprecated lesskey binary format
* less: enable in environment.nix rather than less.nix
