The discussions took place on R-devel, hence some people might not have
Indeed, I think it is possible to provide an srt command (e.g. in half a
year for something like R-2.1.0). What is expected for "srt = 0"?

the margin side to plot the text in, or
b) always horizontally drawn text?
I'd vote for b).
