[Rd] windows testing

[Duncan Murdoch]

1. Tried running "test-all-extras" today.  It failed comparison on the
last of the regression tests, "reg-plot".  As far as I could tell, the
output looked okay.  The differences were in reported values of the
relative range of values, as in 

>> for(j.fac in 1e-12* c(10, 1, .7, .3, .2, .1, .05, .03, .01)) {
>+ ##           ====
>+     #set.seed(101) # or don't
>+     x <- pi + jitter(numeric(101), f = j.fac)
>+     rrtxt <- paste("rel.range =", formatC(relrange(x), dig = 4),"* EPS")
>+     cat("j.f = ", format(j.fac)," ;  ", rrtxt,"\n",sep="")
>+     plot(x, type = "l", main = rrtxt)
>+     cat("par(\"usr\")[3:4]:", formatC(par("usr")[3:4], wid = 10),"\n",
>+         "par(\"yaxp\") :   ", formatC(par("yaxp"), wid = 10),"\n\n", sep="")
>+ }
>j.f = 1e-11 ;  rel.range = 553.9 * EPS
>par("usr")[3:4]:     3.142     3.142
>par("yaxp") :        3.142     3.142         3
>
>j.f = 1e-12 ;  rel.range = 56.02 * EPS
>Warning: relative range of values = 85.307 * EPS, is small (axis 2).
>par("usr")[3:4]:     3.142     3.142
>par("yaxp") :        3.142     3.142      

and some warnings about character widths:

>Warning: font width unknown for character 144
>Warning: font metrics unknown for character 144
>Warning: font width unknown for character 144
>Warning: font width unknown for character 157
>Warning: font metrics unknown for character 157
>Warning: font width unknown for character 157

2.  In test-Internet, the file comparisons were different (in what
looked like trivial ways: the directory and list from CRAN was
different).  The test produced a file "internet.Rout2" that had no
corresponding .save file.
