[moved to R-devel]

The discussions took place on R-devel, hence some people might not have noticed them.

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"? a) the current behaviour, i.e. srt=0 in respect to the las setting *and* the margin side to plot the text in, or
b) always horizontally drawn text?

I'd vote for b).
