That's where the ambiguity comes from.  As they are options to 'set 
term', I would tend to agree with Daniel. If you ask the terminal to 
output in monochrome, you expect everything to be in monochrome.

However, if the above options could be handled by the core, via a 
command 'set default' for example, then Ethan's described behaviour 
makes much more sense.

Ex : 'set default dashed font "Times,4" lw 5 mono' would not prevent 
from override them in particular labels, lines, or whatever.

Implementing these options in the core seems reasonable, not that hard, 
and would save a lot of code duplication in the terminals. One more 
thing on my post-4.2 projects list.

Best regards,

Timothée
