Tweak colors

SGR parameters 90-97 are bright foreground (leaving bold unchanged) and
100-107 are bright background (leaving underline/blink unchanged);
`38;5;#` & `48;5;#` will work for the first 16 colors, setting both
foreground & bold or background & underline (0-7 bold/underline off,
8-15 bold/underline on).
