I don't see how this changes anything

Yeah I think this is just a matter of adding some - probably in the endif. There's a little bit of fiddling to get this sort of thing right. Fortunately the space of parameters to explore is quite small 🙂

Ok, now it works, no double blank lines

[isuruf]

Thanks

[jakirkham]

Thanks Johnny! Know fiddling with Jinja whitespace is a little tedious. We appreciate the effort 🙂

Yes, sorting this out took some time, it doesn't work as I thought it works. This is my last change for conda-smithy, just wanted to assist a user with packaging ACE through conda, now back to my real work ;-)
