Give "all that" even with multiple calcs

Just removes the check before aggressive shortening whether it is only one calc.

Resolves #311

Could you please add a (integration) test with the comment from the issue? #311

Problem is, that test case doesn't break like that, it gives the expected (but maybe not wanted) If I posted all numbers, the comment would get too long. So I had to remove some of them.\n\nFactorial of 99 is roughly 9.332621544394415268169923885627 × 10^155 \n\n\n*^(This action was performed by a bot | [Source code](http://f.r0.fyi))*.

Now the question is, do we want to change the order and first try to reply with "all that" before removing calculations? I think that way makes more sense.

I have in the last commit done that. And added an exception for steps (seemed unreadable to me) and made it so, that, when ops are not nested, "All that of" is not used.
