Looks like a bug to me. I can't presently run the developers sources, but I see 
the same effect in 3.2.

The proper fix would be to properly implement the legend as a separate axes 
object, and have the text labels inherit their parent's interpreter property.

Until then it would be possible to (1) change the legend interpreter to "none", 
or (2) have the legend inherit the interpreter of its axes.

For a quick fix, and if you don't mind the console error it produces, you can 
try the change below

    plot(1:10, 1:10, "-;foo{_}bar;1");
