Labels ignore \t character

[LindsayVass]

I originally encountered this problem when attempting to include \t in facet labels with a custom labeller, but after posting on StackOverflow, this appears to occur any time \t is included in a label.

ggplot(mtcars, aes(mpg, cyl)) + geom_point() + labs(x = "Tab\tneeded", y = "Newline\nneeded")

It doesn't look like R supports tab characters in graphics devices:

plot(1)
text(1, 1, "blah\tblah")
