(what's the paste() for?)

...and it is a design choice of course. Notice that operators are not
boldfaced either, e.g., in text(x=3,y=3, quote(bold("x"==2*a + b ~~ "x
= 2a+b"))) you get the = and the + in non-bold in the first part
(granted, a bit hard to see for =). As I recall it, LaTeX does
similarly unless you jump through a couple of hoops. It is
intentional, but if you try to do it otherwise you'd run into trouble
with the absense of a bold symbol font.
