qt(p,df) discontinuous in p for df in 1.01->1.7 (PR#2991)
...70
Higher df as df=1.1 (and up to approx df=1.7) seem to have problems as it also
gives discontinuities (the plural form!):
plot(seq(0.1,0.9,by=0.001),qt(seq(0.1,0.9,by=0.001),1.1),pch=".")
When df is close to 1 it appears as one discontinuity at p=0.5, and as df
increases there are two discountinuities symmetrical around 0.5 and moving away
from 0.5.
Keep up your outstanding work on R ;-)
