Issues of R_pretty in src/appl/pretty.c
...hey work now.
I mentioned them partly because the commit description said overflow for large n and partly to be considered for regression tests.

That
pretty(c(-1,1)*1e300, n = 1e9, min.n = 1) gave 20 intervals, far from 1e9, but
pretty(c(-1,1)*1e300, n = 1e6, min.n = 1) gave 1000000 intervals
(on a machine), made me trace through the code to function 'R_pretty' in https://svn.r-project.org/R/trunk/src/appl/pretty.c .
*lo is -1e300, *up is 1e300.
cell = fmax2(fabs(*lo),fabs(*up));
'cell' is 1e300.
i_small = dx < cell * U * imax2(1,*ndiv) * DBL_EPSILON *3;
When *ndiv is (int) 1e9, apparently cell * U * imax2(1,*ndiv) overflows to infinity a...
