Unless there is a good reason, can you please keep individual test output fewer than 100 lines? I think the 41-line result is an overkill as well. This just bloats the repository size unnecessarily.
Okay. In this revision i cut the tests' result except the last one (the one that tests values just before numeric overflow).
Also, I see that this patch was added to the 2014-10 commitfest and then deleted again (by user apaan). Why?
User apaan is me. When i added to the commitfest, the patch is listed there by me (apaan). I only added some bits from original patch by Платон Малюгин that was revised further by Michael Paquier. So i think they should have the credits for this patch, not me.
