github: What to do when unittests fail?

[Andrej Mitrovic]

Well my editor automatically converts everything to unix LF when
saving a file. I think this is the standard for Phobos and dpl.org
libs, right? If not, I'll set the editor to just follow whatever line
endings a file has.

It also converts tabs to spaces as well. I think I did see some mixed
use of tabs and spaces in some modules.
