+ + minor cleanup to test/view.c:

+ attribute values which can be stored in those types.
+ + correct array-index when parsing "-T" command-line option in tabs
+ program.
+ + modify demo_new_pair.c to pass extended pairs to setcchar().

+ extended colors which can be contrasted with dots_curses.c.

+ for a terminal emulator may use the combination incorrectly.
