Oh yeah, I see that.  A green sample.  Which sort of makes sense.

Seeing the green line makes me think, yes, it is the first copy, which 
appears to be extraneous.

But what made me wonder is that in example #24 is the function key text 
followed by a blank, thinking that it's blank because the mesh is 
absent.  And then there are a bunch of examples previous to that where 
the mesh is present and the function key text has a sample line the 
color of the mesh.  I suppose in example #24 the text is also extraneous 
and shouldn't appear.

I'll write up a bug report this evening with a patch.
