color: allow for user-configurable terminfo codes for effects If the entry in the terminfo database for your terminal is missing some attributes, it should be possible to create them on the fly without resorting to just making them a color. This change allows you to have [color] terminfo.<effect> = <code> where <effect> might be something like "dim" or "bold", and <code> is the escape sequence that would otherwise have come from a call to tigetstr(). If an escape character is needed, use "\E". Any such settings will override attributes that are present in the terminfo database.
