[Rd] wishlist boxplot (PR#13553)

[ligges at statistik.tu-dortmund.de]

[CCing Martin and Brian who had both done most svn commits of boxplot.R 
so far]


A very minor wishlist item that I should have already reported years ago:

All the time when I need presentation/publication quality boxplots, I 
add par(lend=1) in my code in order to suppress the ugly median line 
that does not stop at the end of the box given the rounded line endings.

Ugly example:

boxplot(1:10, lwd=30)



I'd like the following very minor change for boxplots:
