[Rd] axis() ignores supplied value of argument mgp[3]?

[J. R. M. Hosking]

It seems that when an argument 'mgp' is supplied to axis(),
the mgp[2] value (position of tick mark labels) is honoured
but the mgp[3] value (position of axis line) is ignored.
Example:

   plot(1:5, xaxt='n', ann=FALSE)
   par(mgp=c(0,2,1))
   axis(1, at=2:4, mgp=c(0,-2,-3))

Axis line is plotted at margin line 1, tick mark labels at line -3.

Is this a bug?
