Thanks for the PR @ragnerok , some general feedback:

• could you please use 4 spaces for indentation, like in the rest of the project? Both are fine options but it's best to have the same setting through the whole project, and we'd like to stick to 4.
• could you please add tests which cover the new behavior?

[osaid-r]

@lopuhin I am sorry my text editor was set to 2 spaces, I'll fix it. I'll add a few test cases as well.
