argument srt for mtext(); was: [R] using text on the x axis ticks rather than numbers

Out of curiosity, why is srt not respected in mtext ? See examples below
It doesn't make a lot of sense. mtext is about putting text on >m<argin lines, and even the ability to have text perpendicular to the axis (via las) is rather awkward to interpret (and the interpretation will be changed in 2.0.0). If you are going to rotate text you need to able to specify a point of rotation and that's much easier via text.
It would be nice to have 'srt' as an argument in mtext in future.
You haven't been listening to the discussions pre-2.0.0 on the semantics of `adj' (and now padj as well) in mtext. Experts seem to find it hard to keep even the two current cases (parallel and perpendicular) clear in their minds.
[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).

BTW, if you want to use srt with mtext(at=) you can always use S ....
