6a4c3b61e6 Improve doc of calcHist overload that accepts vectors 
It's not clear how ranges argument should be used in the overload of
calcHist that accepts std::vector. The main overload uses array of
arrays there, while std::vector overload uses a plain array. The code
interprets the vector as a flattened array and rebuilds array of arrays
from it. This is not obvious interpretation, so documentation has been
added to explain the expected usage.

Merge pull request #22149 from seanm:sprintf 
Replaced sprintf with safer snprintf

* Straightforward replacement of sprintf with safer snprintf
