utACK f6f8026 - at this point pindexState == pindex, if e.g. chainActive.Height() == 10 and nCheckDepth == 1, pindex should break at height 9 (<=) rather than 8 (<).

One thing throwing me off about this method: looks like reporting doesn't work if nCheckLevel < 3, because pindexState is always chainActive.Tip(). Is that right?

Yeah, that clearly looks wrong. The report at the end will say 'last 0 blocks'... hm.

Edit: see #13431 for fix.

f618ebc validation: count blocks correctly for check level < 3 (Karl-Johan Alm)
