Lua primitives: unread_message_colour()
When in index-mode, set with global_mode, the display will consist of a list of messages.
Messages which have previously been read will be displayed as white, while unread messages will be coloured red by default.
This function lets you change the colour which unread messages will be drawn in.
Valid colours are "blue", "cyan", "green", "magenta", "red", "white", & "yellow".
-- Show unread messages in green, as that jumps out: unread_message_colour( "green" );
This function has been available since version 0.12.
