in 6251644 the change to the makeflags sed also made it less specific, acting on lines matching "MAKEFLAGS" instead of "^#MAKEFLAGS". the change to the pacman color sed in 1bd9a35 once given the same correction only saves 1 character over the previous commit's more readable expression where "Color" appears twice, so it's reverted to that.
because the pattern ends with ".*" the "$" is useless. also made the sed for uncommenting "Colors" slightly shorter by using "/<pattern>$/s/^#//" instead of "s/^#<pattern>$/<pattern>/"
