As explained in the ChangeLog for this recent addition, it indicates that the
terminal is currently in monochrome mode (usually because of the command
'set term ... monochrome'.  The core code does not use the flag yet.
It was added in preparation for a series of patches that allows the user to
redefine the default sequence of line properties.
  #2004590  	 mechanism to redefine base linetypes
The idea is that even if the terminal is capable of RGB colors, and the 
user redefines linetype N to be purple, if the terminal is currently showing
the TERM_MONOCHROME flag then the core code should interpret "lt 3" as
black and perhaps dashed rather than as purple.
