After upgrading Ubuntu from 15.10 to 16.04, I noticed a problem with
the background color. When I start and leave "mutt" in a terminal
window with a white background, the line with the next prompt will
have a black background. The next "less" command will also have a
black background. The problem goes away after a "reset" command.

This behavior seems to be caused by the following change and reverting
it fixes the problem for me:

20151017
	+ remove an early-return from _nc_do_color, which can interfere with
	  data needed by bkgd when ncurses is configured with extended colors
	  (patch by Denis Tikhomirov).
