Comment(by whuss):
''detect_poles'' is only meant for the case when the left/right side
limits of the function are +/-Infinity.
It was never intended to detect other discontinuities.
But ticket #6878 implements something like this. It does not automatically
detect the discontinuities but
lets you specify which points to exclude from the plot.
The following would have the effect you want:
{{{
sage: plot(ceil(x), (x, 1, 10), exclude = [1..10])
}}}
