How does the quantile function treats/handles nan values in a series

It appears strange to have a proper number value for the 0.8-quantile
and for the 0.9-quantile so that the inequality condition can be
checked, but not for the 0.85-quantile.
Hm, something seems weird with quantile and missings:
<hansl>
m = seq(1,5)'
eval quantile(m, 0.5) # 3, correct
m[4] = NA
print m
eval quantile(m, 0.5) # 1, weird
</hansl>
Hmm, apparently the back-end for quantile() with a matrix argument
was coded on the assumption that any NAs would be screened out in
advance, but that wasn't actually done anywhere. That's now fixed in
git (NAs are skipped). Snapshots will follow tomorrow.
